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. 22325-27-5, name is 2-Mercapto-4,6-dimethylpyrimidine, molecular formula is C6H8N2S, 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. COA of Formula: C6H8N2S

General procedure: The intermediates M1-4 were synthesized according to previously reported methods [8,9]. A solution of thiol (1 mmol) was prepared in 1% aqueous NaOH (5 mL). Then, we added, dropwise, 1 mL of halogenated-methyl flavonoids, M1-4 (1 mmol), in DMF. The mixture was heated to 90 C in an oil bath; alternatively it was sealed, and then irradiated in a Smith Creator microwave at 50-100 W to 90 C. After completion of the reaction, the mixture was diluted with water (40 mL) and the precipitate was filtered. Finally, the precipitate was recrystallized from an appropriate solvent to give the title compounds, 5-8.

With the rapid development of chemical substances, we look forward to future research findings about 22325-27-5.

Electric Literature of 22325-27-5 ,Some common heterocyclic compound, 22325-27-5, molecular formula is C6H8N2S, 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.

Sodium hypochlorite (30.9 mL, 60.0 mmol) was added dropwise with rapid stirring to a solution of 4,6-dimethylpyrimidine-2-thiol (1.40 g, 10.00 mmol) and CaCl2 (14 g) in CH2Cl2 (60 mL) and 1N HCl (55.0 mL, 55.0 mmol) at -23 C. After the addition was complete, the mixture was stirred for 15 min at -23 C. and the phases where separated. The organic layer was transferred to a 250 mL 3-necked flask which was then chilled to -23 C. and equipped with a cold finger (-70 C.). NH3 was bubbled through the reaction mixture for 15 min. and then the reaction was slowly allowed to warm to rt and stirred 16 h. The resulting white precipitate was separated by filtration and the filtrate was concentrated under vacuum to yield 4,6-dimethylpyrimidine-2-sulfonamide (1.003 g, 5.36 mmol, 53.6% yield) as white solid. 1H NMR (300 MHz, acetone-d6) delta ppm 7.43 (s, 1H), 6.63 (br s, 2H), 2.53 (s, 6H). LC-MS retention time 0.39 min; m/z 188 (MH+). LC data was recorded on a Shimadzu LC-10AS liquid chromatograph equipped with a Phenomenex-Luna 10 u C18 4.6¡Á50 mm column using a SPD-10AV UV-Vis detector at a detector wave length of 220 nM. The elution conditions employed a flow rate of 5 ml/min, a gradient of 100% solvent A/0% solvent B to 0% solvent A/100% solvent B, a gradient time of 2 min, a hold time of 1 min, and an analysis time of 3 min where solvent A was 10% MeOH/90% H2O/0.1% trifluoroacetic acid and solvent B was 10% H2O/90% MeOH/0.1% trifluoroacetic acid. MS data was determined using a Micromass Platform for LC in electrospray mode.

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,22325-27-5, its application will become more common.
