実験手順

To a suspension of N-[4-chloro-2-(4-fluorobenzoyl)phenyl]-1H-imidazole-1-carboxamide (63.0 g, 183.3 mmol) in THF (315 mL) was added 2,2,2-trifluoroethylamine (24.5 g, 247.4 mmol). The reaction was heated to 50° C. After 19 h at 50° C., the reaction was cooled to ambient temperature and concentrated in vacuo. The light yellow oil was partitioned between n-butyl chloride (110 mL) and aqueous 10% citric acid (60 mL) with vigorous stirring. The resulting precipitate was collected by vacuum filtration and placed under vacuum alongside P2O5 for 16 h to give 6-chloro-4-(4-fluorophenyl)-4-hydroxy-3-(2,2,2-trifluoroethyl)-3,4-dihydroquinazolin-2(1H)-one as an off-white solid.
