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.1208170-17-5, name is 4-Chloro-6-methyl-2-(methylthio)pyrimidine-5-carbonitrile, molecular formula is C7H6ClN3S, molecular weight is 199.66, as common compound, the synthetic route is as follows.category: pyrimidines

To a round bottomed flask was added (5)-1-(1-methyl-6-(1-methyl-1H-pyrazol-5-yl)-1H-pyrrolo[3,2-b]pyridin-5-yl)ethanamine 2,2,2-trifluoroacetate (364 mg, 0.986 mmol) in THF (6400 mu) along with 4-chloro-6-methyl-2-(methylthio)pyrimidine-5 -carbonitrile (197 mg, 0.986 mmol) and Et3N (302 muEpsilon, 2.168 mmol). The reaction mixture was stirred at room temperature overnight and was subsequently purified on silica, eluting with a gradient of EtOAc/hexanes (2:8 to 9: 1) to give the title compound as a clear film (270 mg, 65.5%). ESI- MS m/z [M+H]+ calc’d for C21H22N8S 419.17; found 419.4.
