Reaction Steps

A solution of ethyl 6-hydroxy-2-(2-propoxyphenyl)pyrimidine-4-carboxylate (0.44 g) in aqueous ammonia solution (20 ml) was stirred in a stoppered flask at ambient temperature for 4 hours and then allowed to stand for 3 days. The reaction mixture was acidified with concentrated hydrochloric acid to precipitate the title compound, 0.46 g, m.p. 232°-4° C. This was recrystallized from ethanol:methanol to yield the pure title compound, 0.32 g, m.p. 233.5°-234.5° C.
