In analogy to the method described in example A1, 3.67 g (22.8 mmol) of 4-amino-5-chloro-2,6-dimethylpyrimidine, 6.0 g (22.8 mmol) of 4-benzyloxy-3-methoxybenzyl chloride and 0.91 g (23 mmol) of sodium hydride (60% suspension in liquid paraffin) are reacted in a total of 190 ml of N-methylpyrrolidone. After chromatography on silica gel (mobile phase: toluene/dioxane=10:1) and crystallization from petroleum ether, the title compound is isolated as a pale beige solid. Yield: 3.42 g (39% of theory). m.p.: 101-105° C.
