Reaction Steps
N-(2-Fluoro-5-aminophenyl)benzamide (276 mg) was added to a suspension of 4-chloro-6,7,8-trimethoxyquinazoline hydrochloride (293 mg) in isopropanol (8 ml) and the resultant mixture stirred and heated to 80° C. for 18 hours. The mixture was cooled to ambient temperature and the precipitated solid was isolated, washed with isopropanol then diethyl ether to yield the title compound as a solid (257 mg, 53%); NMR: 4.0 (s, 3H), 4.01 (s, 3H), 4.07 (s, 3H), 7.42 (t, 1H), 7.52 (m, 2H), 7.62 (m, 2H), 8.0 (m, 3H), 8.35 (s, 1H), 8.72 (s, 1H), 10.28 (s, 1H), 11.84 (broad s, 1H); m/s: M+H+ 449.
