実験手順
N-Cyclopropyl-N-{1-[3-(2-hydroxyethylamino)hexanoyl]piperidin-4-yl}-3-trifluoromethylbenzenesulfonamide (40) was prepared by reacting N-cyclopropyl-N-(1-hex-2-enoyl-piperidin-4-yl)-3-trifluoromethyl-benzenesulfonamide (250 mg, 0.56 mmol) and ethanolamine (2 mL) as described in Example 26 above. The reaction mixture was cooled and partitioned between ether (100 mL) and 1M sodium hydroxide solution (100 mL). The organic phase was separated, dried (MgSO4) and the solvent evaporated to dryness in vacuo to leave a colourless gum. The residue was chromatographed over flash silica eluting with ethyl acetate:methanol:ammonia (100:10:1) to give the free base 40 (100 mg). This was converted to the fumarate salt (95 mg, 27%) which was a white solid. LC: 100%. MS: m/z=506.2, 507.3, 508.2 (M+H). 1H NMR (400 MHz, DMSO-d6): (1:1 mixture of rotamers) δ 8.22 (1H, d, J=7.5 Hz), 8.13 (2H, m), 7.92 (1H, t, J=7.5 Hz), 6.47 (1H, s), 4.43 (1H, d, J=13.3 Hz), 4.10 (1H, t, J=13.3 Hz), 3.88 (1H, d, J=13.3 Hz), 3.55 (2H, m), 3.25 (1H, m), 3.05 (1H, t, J=13.3 Hz), 2.85 (2H, m), 2.70-2.50 (3H, m), 1.96 (1H, m), 1.80-1.20 (8H, m), 0.88-0.65 (7H, m).
