To a solution of 4-chloro-6-methyl-2-(6-n-propyl-2-pyridinyl)pyrimidine (1 g) in methanol (10 ml), was added sodium methoxide prepared from methanol (10 ml) and metallic sodium (0.11 g). After being left to stand at room temperature for two hours, the solution was concentrated under reduced pressure. To the residue obtained, was added chloroform (100 ml). The mixture was washed twice with water (30 ml each) and dried over anhydrous magnesium sulfate. The extract was concentrated under reduced pressure to obtain 4-methoxy-6-methyl-2-(6-n-propyl-2-pyridinyl)pyrimidine (0.93 g, yield: 95 %).
