The origin of a common compound about 4-Bromo-6-hydroxypyrimidine

The chemical industry reduces the impact on the environment during synthesis 1086382-38-8, I believe this compound will play a more active role in future production and life.

Reference of 1086382-38-8, With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.1086382-38-8, name is 4-Bromo-6-hydroxypyrimidine, molecular formula is C4H3BrN2O, molecular weight is 174.98, as common compound, the synthetic route is as follows.

Step A: 6-Bromo-3-methylpyrimidin-4(3H)-one To a solution 6-bromopyrimidin-4(3H)-one (696 mg, 2.0 mmol) in DMF (3.0 mL) was added K2CO3 (828 mg, 6.0 mmol), CH3I (568 mg, 4.0 mmol), the reaction mixture was stirred at 50 C for 30 minutes. The mixture was cooled to ambient temperature, diluted with EtOAc (20 mL), washed with sodium bicarbonate (10 mL) and brine (10 mL), dried over MgS04, filtered and concentrated. The residue was purified with silica gel column (Petroleum ether : ethyl acetate = 1 : 1) to obtaine product: LC/MS m/z = 189.01 (M+H) +.

The origin of a common compound about 313339-35-4

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 313339-35-4, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carboxylic acid, other downstream synthetic routes, hurry up and to see.

Reference of 313339-35-4, Adding some certain compound to certain chemical reactions, such as: 313339-35-4, name is 4,6-Dichloro-2-(methylthio)pyrimidine-5-carboxylic acid,molecular formula is C6H4Cl2N2O2S, 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 313339-35-4.

To a suspension of 4, 6-dich.oro-2-methylsulfanylpyrimidine-5-carboxyiic acid (2.1 mmol) inCH2CI2 (20 ml) are added oxalyl chloride (4.2 mmol) and one drop of DMF at 0 C. Afterstirred at room temperature for 3 h under N2 atmosphere, the reaction mixture isconcentrated and dried in vacuo, to give 4, 6~dichloro-2-methylsulfanylpyrimidine-5-carbonylchloride as a yellow crystal.

In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 313339-35-4, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carboxylic acid, other downstream synthetic routes, hurry up and to see.
