In the same way as that described in Example 11, Step 2, using 1-(ethylsulphonylaminocarbonyl )-3-nitrobenzene (3 g, 11.6 mmol), 10% palladium on carbon (0.3 g, 10% (w/w)) in water (3 ml) and ethanol (100 ml), the title compound (1.95 g, 74%) was afforded as a pale beige solid after recrystallisation from ethanol. mp 129°-132° C. 1H NMR (360 MHz, D6 -DMSO) δ 1.24 (3H, t, J=7.4 Hz), 3.47 (2H, q, J=7.4 Hz), 5.40 (2H, brs), 6.77-6.83 (1H, m), 7.02-7.08 (2H, m), 7.13 (1H, dd, J=7.8 and 7.7 Hz).
