Reaction Steps

The title compound was prepared in the same way as that described in Example 11, Step 4, using 5-cyclohexyl-l,3-dihydro- 1-methyl-3(R,S)-[(4-nitrophenyloxycarbonyl)amino]-2H-1,4-benzodiazepin-2-one (0.3 g, 0.69 mmol), triethylamine (96 μl, 0.69 mmol), dimethylformamide (6 ml) and 1-(isopropylsulphonylaminocarbonyl)-3-aminobenzene (0.175 mg, 0.72 mmol). After recrystallisation from ethanol the title compound (0.24 g, 65%) was afforded as a colourless solid. mp 165° C. (dec.). 1H NMR (360 MHz, D6 -DMSO) δ 0.87-0.98 (1H, m), 1.10-1.64 (7H, m), 1.30 (6H, d, J=6.9 Hz), 1.79 (1H, m), 1.88-1.96 (1H, m), 2.95 (1H, m), 3.33 (3H, s), 3.79 (1H, septet, J=6.9 Hz), 5.07 (1H, d, J=8.2 Hz), 7.37 (3H, m), 7.46 (1H, d, J=7.8 Hz), 7.55 (2H, m), 7.64 (1H, dd, J=7.1 and 7.1 Hz), 7.75 (1H, d, J=7.9 Hz), 7.92 (1H,s), 9.22 (1H,s), 11.93 (1H, brs).
