実験手順

In the same way as that described in Example 11, Step 2, using 1-(phenylsulphonylaminocarbonyl)-3-nitrobenzene (5 g, 16 mmol), 10% palladium on carbon (0.5 g, 10% (w/w)) in water (3 ml) and ethanol (100 ml), the title compound (3 g,67%) was afforded as a pale beige solid after recrystallisation from ethanol. mp 135°-138° C. 1H NMR (360 MHz, D6 -DMSO) δ 6.75-6.78 (1H, m), 6.96-6.98 (2H, m), 7.10 (1H, dd, J=8.0 and 8.0 Hz), 7.60-7.73 (3H, m), 7.97 (2H, m).
