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%). 1H NMR Spectrum: (DMSOd6) 3.90(s, 3H); 5.36(s, 2H); 7.18(s, 1H); 7.45(m, 2H); 7.46(s, 1H); 7.59(s, 1H); 8.42(d, 1H) MS-ESI: 318 [MH]+
