Reference of 878650-31-8, The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 878650-31-8, name is Methyl 2,6-dichloro-5-methoxypyrimidine-4-carboxylate. This compound has unique chemical properties. The synthetic route is as follows.
Example 6 Preparation of methyl 6-amino-2-chloro-5-methoxy-pyrimidine-4-carboxylate (Head C) A solution of methyl 2,6-dichloro-5-methoxy-pyrimidine-4-carboxylate (25 g, 0.1 mol) and dimethyl sulfoxide (DMSO) was prepared. To this solution was added, at 0-5 C., a solution of ammonia (2 equivalents (equiv) in DMSO). This mixture was stirred at the same 0-5 C. temperature for 10 to 15 min. Later, the mixture was diluted with ethyl acetate, and the resulting solid was filtered off. The ethyl acetate filtrate was washed with a brine solution and dried over sodium sulfate. Upon concentration, the crude product was obtained. The crude product was stirred in a minimum amount of ethyl acetate and filtered to obtain the pure compound. Additional pure compound was obtained from the filtrate which, after concentration, was purified by flash chromatography. This produced the title compound (11 g, 50%): mp 158 C.; 1H NMR (DMSO-d6) delta 3.71 (s, 3H), 3.86 (s, 3H), 7.65 (brs, 1H), 8.01 (brs, 1H).
According to the analysis of related databases, 878650-31-8, the application of this compound in the production field has become more and more popular.
