7-(2-(Imidazol-1-yl)ethoxy)-6-methoxy-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin-4-one → 7-(2-(Imidazol-1-yl)ethoxy)-6-methoxy-3,4-dihydroquinazolin-4-one

Participants

Reaction Steps

A solution of 7-(2-(imidazol-1-yl)ethoxy)-6-methoxy-3-((pivaloyloxy)methyl)-3,4-dihydroquinazolin-4-one (640 mg, 1.6 mmol) in saturated methanolic ammonia (10 ml) was stirred for 15 hours at ambient temperature. The volatiles were removed by evaporation, the solid was triturated with ether, collected by filtration and dried under vacuum to give 7-(2-(imidazol-1-yl)ethoxy)-6-methoxy-3,4-dihydroquinazolin4-one (412 mg, 90%).
