실험 절차

The title compound was prepared from a mixture of 5-chloro-2-[(isopropylamino) sulfonyl]benzoic acid and 3-chloro-4-[(isopropyl amino)sulfonyl]benzoic acid 2d and endo 2-methyl-1-{8-[2-(4-phenylpiperidin-4-yl)ethyl]-8-azabicyclo[3.2.1]oct-3-yl}-1H-benzimidazole dihydrochloride II following the general procedure for tert-butyl {2-[(4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenyl piperidin-1-yl)carbonyl]phenyl}sulfonylcarbamate 1c. The desired regioisomer was purified by column chromatography on silica gel eluting with 10% methanol in ethyl acetate to afford 4-chloro-N-isopropyl-2-[(4-{2-[3-(2-methyl-1H-benzimidazol-1-yl)-8-azabicyclo[3.2.1]oct-8-yl]ethyl}-4-phenyl piperidin-1-yl)carbonyl]benzenesulfonamide 4 as a white solid (30 mg, 22% yield). 1H NMR (400 MHz, CDCl3) δ 8.13 (d, 1H, J=8.0 Hz), 7.65 (d, 1H, J=7.3 Hz), 7.52 (m, 1H), 7.40-7.11 (m, 9H), 4.99 (d, 1H, J=7.32 Hz), 4.60 (m, 1H), 4.20 (m, 1H), 3.49-3.22 (m, 6H), 2.56 (s, 3H), 2.40-2.32 (m, 3H), 2.18 (m, 1H), 1.98-1.66 (m, 1H), 1.62 (m, 2H), 1.10 (d, 6H, J=6.59 Hz). ES-LCMS m/z 690.45 (M+2H). Analytical HPLC (Method Y) Rt 5.03 (88.43%).
