Reaction Conditions

Reaction Steps

To an emulsion of 6-benzyl-2,4-dichloro-pyrimidine (239 mg, 1 mmol) in 25% aqueous ammonia solution (1 mL) was added after stirring for 10 min at 0° C. zinc powder (82 mg, 1.25 mmol). The reaction was stirred at 20° C. for 16 h. The yellow suspension was diluted with ethyl acetate an insoluble material was filtered off. The layers were separated and the aqueous layer was extracted with ethyl acetate. The combined organic layers were washed with brine, dried over sodium sulfate and evaporated under reduced pressure to yield the crude title compound (210 mg, 92%) as a yellow oil.
