Procedure
Sodium methylate in methanol (112 ml of a 5.4 molar solution) is added at room temperature to a solution of methyl 4,6-dichloro-pyrimidin-5-yl-acetate (120 g, 0.54 mol) in 1,2-dimethoxyethane (200 ml) with cooling. The reaction mixture is stirred for 30 minutes and poured on crushed ice. The precipitated crystals are filtered and dried to give the methyl 4-chloro-6-methoxy-pyrimidin-5-yl-acetate (106 g), m.p. 64° C.
