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.33097-13-1, name is 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile, molecular formula is C6H3Cl2N3S, molecular weight is 220.08, as common compound, the synthetic route is as follows.Safety of 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile
Example 43 Synthesis of 5-(4-(2-cyano-3-cyclopropylacrylamido)benzylamino)-7-(3,5-dimethoxyphenylamino)-imidazo[1,2-c]pyrimidine-8-carboxamide Step 1. To a solution of 4,6-dichloro-2-(methylthio)pyrimidine-5-carbonitrile (14 g, 63.6 mmol, 1.0 eq) and 3,5-dimethoxyaniline (9.94 g, 63.6 mmol, 1.0 eq) in THF (300 mL) at 0 C., was added DIEA (12.32 g, 95.4 mmol, 1.5 eq). The resulted mixture was stirred at RT for 4 h. The reaction mixture was diluted with water (30 mL), filtered and dried to give 4-chloro-6-(3,5-dimethoxy-phenylamino)-2-methylsulfanyl-pyrimidine-5-carbonitrile (19 g, 89% in yield).
At the same time, in my other blogs, there are other synthetic methods of this type of compound,33097-13-1, 4,6-Dichloro-2-(methylthio)pyrimidine-5-carbonitrile, and friends who are interested can also refer to it.
