Procedure

1,3-Dihydro-3-(RS)-amino-5-(2-fluorophenyl)-2H-1,4-benzodiazepin-2-one (42 mg, 0.156 mmole) and p-trifluoromethylbenzoyl chloride (32.5 mg, 0.156 mmole) were combined in 3 ml of methylene chloride (CH2Cl2), treated with triethylamine (0.0157 g, 0.156 mmole) and stirred at room temperature 15 minutes. The mixture was diluted with CH2Cl2 (20 ml), washed with 10% citric acid (2×5 ml), dilute sodium bicarbonate (2×5 ml), and water (2×5 ml), dried over sodium sulfate, filtered, and evaporated to dryness in vacuo. The residue was crystallized from ethyl acetate (0.4 ml)/ether (1 ml) to give the title compound which was dried in vacuo at 90°: (m.p. 209°-211°).
