実験手順

To a solution of (3RS)-3-amino-2,3-dihydro-1-ethoxycarbonylmethyl-5-(2-fluorophenyl)-1H-1,4-benzodiazepin-2-one (1.972 g) in dichloromethane (15 ml) was added dropwise a solution of m-tolyl isocyanate (0.884 g) in dichlromethane (5 ml) under stirring. After completion of the addition, the mixture was stirred for 4 hours at ambient temperature. The resultant white precipitates were collected by suction to give N-[(3RS)-2,3-dihydro-1-ethoxycarbonylmethyl-5-(2-fluorophenyl)-2-oxo-1H-1,4-benzodiazepin-3-yl]-N'-(3-methylphenyl)urea as a colorless crystalline solid (1.533 g). The filtrate was concentrated in vacuo. The residue was treated with chloroform and isopropyl ether to recover the desired compound (0.897 g).
