At the same time, in my other blogs, there are other synthetic methods of this type of compound,5018-38-2, 4,6-Dichloro-5-methoxypyrimidine, and friends who are interested can also refer to it.

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.5018-38-2, name is 4,6-Dichloro-5-methoxypyrimidine, molecular formula is C5H4Cl2N2O, molecular weight is 179, as common compound, the synthetic route is as follows.Quality Control of 4,6-Dichloro-5-methoxypyrimidine

General procedure: To a solution of amine (320 mg, 0.8 mmol) in N-methyl-2-pyrrolidone (6 mL) was added diisopropylethylamine (270 mg, 2 mmol). The solution was stirred for 5 mm at room temperature at which time 4,6-dichloro-5-methoxypyrimidine (150 mg, 0.8 mmol) was added. The reaction mixture was stirred at 80C overnight then allowed to cool to room temperature. Water was added and the resulting mixture was extracted with methyl tert-butylether (3x). The combinedorganic layers were washed with water, dried over sodium sulfate, and concentrated in vacuo. The residue was purified by HPLC to provide 139mg (0.3 mmol, 37%) of the light yellow oily product.
