Procedure

3-[6-{4-[5-(Nitro)pyridin-2-yl]piperazin-1-yl}-4-[4-fluorophenyl]-2-(trifluoromethyl)pyrimidin-5-yl]benzenesulfonamide (0.13 g, 0.22 mmol) was taken in concentrated hydrochloric acid (1.5 ml) and to this tin (II) chloride dihydrate (0.145 g, 0.65 mmol) was added and the reaction mixture was stirred for 24 hours at room temperature. Subsequently the reaction mixture was poured onto crushed ice, neutralized with sodium bicarbonate, and extracted with ethyl acetate. Evaporation of the solvent yielded the required product. 1H-NMR (DMSO-d6) δ: 3.13 (m, 4H), 3.30 (m, 4H), 4.58 (br, 2H, D2O exchangeable), 6.57-6.59 (m, 1H), 6.88 (d, 1H), 7.04-7.09 (m, 2H), 7.12-7.14 (m, 2H), 7.39 (br, 2H, D2O exchangeable), 7.41 (d, 1H), 7.50-7.55 (m, 2H), 7.73-7.77 (m, 2H). MS m/z: 574.1 (M++1).
