Hazard Information | Back Directory | [Synthesis]
A convenient synthesis of 4, 6-dihydro-2-methyl-pyrimidine can be obtained by cyclization reaction of acetamidine hydrochloride and diethyl malonate in the presence of sodium methoxide for a 91.2 % yield. 4, 6-Dihydro-2-methyl-5-nitropyrimidine can be achieved by nitration under the mixed acids of nitric acid, trichloroacetic acid and acetic acid in an 88.3 % yield and then the chlorination using phosphorus oxytrichloride can afford 4,6-Dichloro-2-methyl-5-nitropyrimidine with an 82.6 % yield.
