Participants

Reaction Steps

1,3-Dihydro-5-(2-fluorophenyl)-3(RS)-aminomethyl-2H-1,4-benzodiazepin-2-one (80 mg, 0.282 mmole) and indole-2-carbonyl chloride (53 mg, 0.30 mmol) were mixed in 5 ml of methylene chloride at room temperature. The homogeneous reaction mixture was protected from moisture and treated with 42 l (0.30 mmole) of triethylamine. Within five min., triethylamine hydrochloride precipitated. The reaction mixture was stirred at room temperature overnight and then partitioned between methylene chloride and saturated sodium bicarbonate solution. The resulting solid was collected, washed with water and dried over P2O5 at 70° C. In this way, 39 mg of the analytical product was obtained, m.p.: 315°-317° (d).
