Reaction Steps

4-(N-Cyclobutylsulphamoyl)nitrobenzene (Method 52; 11.79 g) was reduced by hydrogenation in ethanol (300 ml) over 10% palladium on carbon (1 g) at 3 bar pressure. The catalyst was removed by filtration and the volatiles evaporated to give the title compound (7.84 g). NMR: 1.50 (m, 2H), 1.75 (m, 2H), 1.93 (m, 2H), 3.60 (m, 1H), 5.90 (br s, 2H), 6.65 (d, 2H), 7.45 (d, 2H); m/z: 226.
