반응 단계
7-Fluoro-3H-quinazolin-4-one: A mixture of 2-amino-4-fluorobenzoic acid (14.6 g, 94 mmol) and formamidine acetate (19.6 g, 18.8 mmol) in 2-methoxyethanol (110 mL) was heated at 130° C. for 18 h. After cooling, the mixture was half evaporated and an off-white solid formed. The mixture was diluted with ammonia (25%, 10 mL in 90 mL water) and the solid filtered off and washed with water. The solid was then washed with hexane and dried under high vacuum to afford the title compound (12.5 g, 81%) as an off-white solid. MS: m/e=165.2 (M+H+).
