Procedure

To a solution of 7-chloro-1,3-dihydro-3-isothiocyanato-1-methyl-5-phenyl-2H-1,4-benzodiazepin-2-one (INTERMEDIATE 7) (0.342 g, 1 mmol) in dichloromethane (20 ml) was added N,N-dimethyl-1,4-benzenediamine (0.136 g, 1 mmol). The reaction mixture was heated at reflux 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 (0.167 g, 35%). 1H-NMR (CDCl3): δ 7.70-7.22 (m, 10H), 6.75 (d, J=8.8 Hz, 2H), 6.05 (d, J=7.6 Hz, 1H), 3.42 (s, 3H) and 2.98 (s, 6H). MS (ESI) (M+H)+=478.
