To an ether solution of benzoyl chloride 2.81 g (0.02 mol) there was added dropwise 1.67 g (0.02 mol) 1-methylimidazole with stirring. The resulting mixture was evaporated in vacuo and the residue was allowed to react with 2.12 g (0.02 mol) benzaldehyde at 70° overnite. After cooling, the reaction mixture was triturated with ether and was solid separated by filtration. Recrystallization from dichloromethane:dioxane gave 4.2 g (0.012 mol), 65%, 9, mp 199°-201°; ir (KBr) 1740 cm-1 ; pmr (CDCl3) δ 4.17 (s, 3H), 8.18-7.25 (m, 12H), 8.50 (s, 1H) and 11.1 (bs, 1H) ppm.
