実験手順
Ammonium formate (1.1 g, 17.46 mmol) followed by a slurry of 10% palladium on carbon catalyst (0.7 g) in ethanol was added in portions to a suspension of 4-[N-(2-Hydroxy-3-piperidinopropyl)sulphamoyl]nitrobenzene (Method 117; 1.2 g, 3.5 mmol) in ethanol (100 ml). The mixture was heated at reflux under nitrogen for 2 hours. The mixture was cooled and the catalyst was removed by filtration through diatomaceous earth. The filter pad was washed with ethanol and the combined filtrates were evaporated. The residue was triturated with diethyl ether, collected by filtration and dried, to give the title compound (0.93 g, 85%) as a pale green solid. NMR: 1.3-1.5 (m, 6H), 2.10-2.32 (m, 6H), 2.60 (m, 1H), 2.75 (m, 1H), 3.52 (m, 1H), 4.50 (brs, 1H), 5.85 (s, 2H), 6.59 (d, 2H), 6.98 (brs, 1H), 7.39 (d, 2H); m/z: 314.
