Systhesis route: Its preparation methods is to join in the reaction bottle, 4, 6 - dihydroxy - 2 - methyl pyridine sulfur and phosphorus oxychloride, reaction hours under nitrogen protection, decompression evaporate to excessive amounts of phosphorus oxychloride, coarse product washing to brown solid sulfur is 4, 6 - dichloro - 2 - methyl pyridine. The pyrimidine was then placed in three vials and added with sodium methanol methanol methanol solution. The reaction lasted several hours. Then add 4, 6 in the other tourism mouth bottle sulfur - dimethoxy - 2 - methyl pyridine, add a small amount of catalyst, add 30% hydrogen peroxide solution, 50 ℃ reaction for several hours, reactant with ethyl acetate extraction, desolventizing, finished product.
