Procedure
To a solution of 3-amino-7-chloro-5-phenyl-1,3-dihydro-1-methyl-2H-1,4-benzodiazepin-2-one (INTERMEDIATE 1) (0.299 g, 1 mmol) in dichloromethane (15 ml) was added 1-isocyanato-4-methoxy-2-methyl-benzene (0.163 g, 1 mmol). The reaction mixture was stirred at room temperature for 17 hours. The solvent was evaporated in vacuo, the residue was triturated with ether and the title compound was obtained as a colorless solid (0.197 g, 42%). 1H-NMR (CDCl3): δ 7.57-7.48 (m, 3H), 7.47-7.44 (m, 1H), 7.39-7.38 (m, 3H), 7.36-7.29 (m, 2H), 6.77-6.73 (m, 2H), 6.71 (d, J=2.8 Hz, 1H), 6.61 (s, 1H), 5.51 (d, J=8.4 Hz, 1H), 3.78 (s, 3H), 3.39 (s, 3H) and 2.29 (s, 3H). MS (ESI) (M+H)+=463.
