Reaction Steps

A mixture of 7-((2-chloro-4-pyridyl)methoxy)-6-methoxy-4-phenoxyquinazoline (260 mg, 0.7 mmol) and 2M hydrochloric acid (15 ml) was heated at 85° C. for 2 hours. The mixture was allowed to cool and adjusted to pH6-7 with sodium hydrogen carbonate solution. The resulting precipitate was collected by filtration and dried to give 7-((2-chloro-4-pyridyl)methoxy)-6-methoxy-3,4-dihydroquinazolin-4-one (160 mg, 76%).
