In methanol; at 20.0℃; for 37.0h;Cooling with ice; | Reference Example 179 4-Chloro-6-methoxy-2-methyl-5-nitropyrimidine To a solution of 4,6-dichloro-2-methyl-5-nitropyrimidine (6.54 g) in methanol (31.5 mL) was added sodium methoxide (28% methanol solution, 6.05 mL) in a dropwise manner under ice-cooling, and the mixture was stirred at the same temperature for 1 hour, and then stirred at room temperature for 1.5 days. The reaction mixture was poured into water, and the resulting mixture was extracted with diethyl ether. The extract was washed with water and brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane - n-hexane/ethyl acetate = 9/1) to give the title compound (5.7 g). |
