The title compound was prepared from 5-cyclohexyl-1,3-dihydro-l-(2-methylpropyl)-3(R,S)-[(4-nitrophenyloxycarbonyl)amino]-2H- 1,4-benzodiazepin-2-one (0.3 g, 0.63 mmol), triethylamine (87 μl, 0.63 mmol), dimethylformamide (6 ml) and 1-(methylsulphonylaminocarbonyl)-3-aminobenzene (0.15 g, 0.69 mmol) [Example 16, Step 2] using the procedure described in Example 11, Step 4. The product (0.17 g, 49%) was afforded as a pale cream solid after trituration with methanol. mp 250°-252° C. 1H NMR (360 MHz, D6 -DMSO) δ 0.64 (3H, d, J=6.6 Hz), 0.76 (3H, d, J=6.7 Hz), 0.92-1.70 (9H, m), 1.74-1.82 (1H, m), 1.98 (1H, m), 2.90-3.30 (1H, m), 3.33 (3H, m), 3.62 (1H, dd, J=14.0 and 4.7 Hz), 4.14 (1H, dd, J=13.9 and. 9.4 Hz), 5.04 (1H, m), 7.37 (3H, m), 7.47 (1H, m), 7.60 (3H, m) , 7.78 (1H, m), 7.90 (1H, s), 9.18 (1H, s), 12.06 (1H, brs).
