Related Products of 14080-23-0, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 14080-23-0, name is 2-Cyanopyrimidine, molecular formula is C5H3N3, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

Step A: Preparation of methylpyrimidine-2-carboxylate: HCl gas was bubbled through methanol (“MeOH”, 700 mL) at a temperature of 0 C. for 30 minutes to give a saturated solution. Pyrimidine-2-carbonitrile (21.585 g, 205.38 mmol) was added to this solution, and the mixture was stirred at room temperature for 16 hours and then at a temperature ranging from about 40 to about 50 C. for 3 hours. The reaction mixture was concentrated, and the residue was dissolved in water. The pH was adjusted to about 7.0 using solid NaHCO3. The aqueous layer was extracted with 20% isopropyl alcohol (“iPrOH”)/dichloromethane (“DCM”) (3*). The combined organics were dried over sodium sulfate, filtered and concentrated under vacuum to give the desired product as white solids (23.0 g, 81%). 1H NMR (400 MHz, CDCl3) delta 8.97-8.96 (d, J=4.7 Hz, 2H), 7.53-7.50 (t, J=4.7 Hz, 1H), 4.09 (s, 3H).

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 14080-23-0, 2-Cyanopyrimidine.

Adding a certain compound to certain chemical reactions, such as: 14080-23-0, 2-Cyanopyrimidine, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, name: 2-Cyanopyrimidine, blongs to pyrimidines compound. name: 2-Cyanopyrimidine

(i) Synthesis of pyridine-2-carboxyamidrazone A synthesis scheme of pyridine-2-carboxyamidrazone is shown in (E-1). In a 50 mL recovery flask were placed 3.2 g (3.0 mmol) of 2-cyanopyridine, 15 mL of ethanol, 5.0 mL of water, and 2.0 mL (41 mmol) of hydrazine monohydrate. This solution was stirred at room temperature for 26 hours under a nitrogen stream. After a certain time, a saturated saline was added to the solution. This solution was extracted with chloroform, and the extract was dried with magnesium sulfate. The mixture was subjected to gravity filtration, and the obtained filtrate was concentrated to give 1.7 g of a target substance, yellow oily substance in a yield of 40%.

The synthetic route of 14080-23-0 has been constantly updated, and we look forward to future research findings.

Application of 14080-23-0, Adding some certain compound to certain chemical reactions, such as: 14080-23-0, name is 2-Cyanopyrimidine,molecular formula is C5H3N3, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 14080-23-0.

To a stirring solution of 2-cyanopyrimidine (2.0 g, 19.0 mmol) in methanol (50 mL) were added 10%Pd/C (300 mg), 12 N HCI (1.5 mL) under 2 atmosphere. The reaction mixture was stirred under atmosphere (balloon pressure) at RT for 3 h. After consumption of the starting material (by TLC), the reaction mixture was filtered through a pad of celite and the pad was washed with methanol. Obtained filtrate was concentrated under reduced pressure to afford crude compound which was triturated with diethyl ether to obtained compound 2S-Y (1.2 g, 44%) as white solid. 1H-NMR: (500 MHz, DMSO-i): delta 8.87 (d, J= 5.0 Hz, 2H), 8.69 (br s, 2H), 7.52 (t, J= 5.0 Hz, 1H), 4.24 (s, 2H); Mass (ESI): 1 10.3 [M++l]

Synthetic Route of 14080-23-0 ,Some common heterocyclic compound, 14080-23-0, molecular formula is C5H3N3, its traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc., below Introduce a new synthetic route.

Pyrimidine-2-carboxylic acid (11):To a stirred solution of pyrimidine-2-carbonitrile (10) (201 mg, 1.914 mmol) in water (5 mL), KOH (214.3 mg, 3.83 mmol) was added and the reaction was refluxed for 3 h. After consumption of the starting material (by TLC), the reaction was slowly brought to RT, neutralized with 2N HC1 and water was removed from the reaction mixture to give the crude residue which was extracted with EtOAc. The combined organic extracts were filtered through a pad of celite and the filtrate was concentrated under reduced pressure to provide compound 11 (84 mg, 35.4%) which was carried for the next step without any purification.TLC: 80% EtOAc/Hexane (Rf: 0.05)1H NMR (400MHz, CD3OD-d4): delta 8.83 (br s, 2H), 7.47 (t, J = 4.8 Hz, 1H).
