In the same way as that described in Example 11, Step 2, using 1-(phenylcarbonylaminosulphonyl)-3-nitrobenzene (5.3 g, 17.3 mmol), 10% palladium on carbon (0.5 g, 9% (w/w)) in water (3 ml) and ethanol (100 ml), the title compound (4.3 g, 90%) was afforded as a yellow solid. mp 160°-162° C. 1H NMR (360 MHz, D6 -DMSO) δ 6.81 (1H, m), 7.07 (1H, m), 7.22 (2H, m), 7.48 (2H, m), 7.60 (1H, dd, J=7.4 and 7.4 Hz), 7.87 (2H, m).
