Versuchsvorschrift

A mixture of crude tert-butyl {2-[(4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenylpiperidin-1-yl)carbonyl]phenyl}sulfonyl carbamate 1c and 4N HCl in dioxane (3 mL) was stirred at RT for 2 h. The reaction mixture was partitioned between dichloromethane and saturated aqueous sodium bicarbonate. The organic layer was dried and concentrated and the residue was purified by prep. HPLC (Method Y) to provide 2-[(4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenylpiperidin-1-yl)carbonyl]benzenesulfonamide 1 as a white solid (45 mg, 16% yield). 1H NMR (300 MHz, DMSO) δ 8.05 (m, 1H), 7.63 (m, 3H), 7.39-7.15 (m, 9H), 5.61 (m, 2H), 4.60 (m, 1H), 4.38 (m, 1H), 3.43-3.04 (m, 5H), 2.54 (s, 3H), 2.35-2.17 (m, 4H), 2.13-1.40 (m, 12H). ES-LCMS m/z 612.25 (M+H). Analytical HPLC (Method W) Rt 7.59 (95.89%).
