Versuchsvorschrift
In analogy to the method described in example A1, 6.11 g (38 mmol) of 4-amino-5-chloro-2,6-dimethylpyrimidine, 10.5 g (40 mmol) of 3-benzyloxy-4-methoxybenzyl chloride and 1.52 g (38 mmol) of sodium hydride (60% suspension in liquid paraffin) are reacted in a total of 225 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: 5.2 g (36% of theory). m.p.: 111-117° C.
