This compound was prepared from the hydrochloride salt of 2-[1-(4-amino-cyclohexyl)-5-methyl-1H-benzoimidazol-2-yl]-propan-2-ol (prepared as cis/trans-isomer mixture) and 5-chloro-indan-2-carbaldehyde. The less polar of the two substances isolated by chromatography gave cis-2-(1-{4-[(5-chloro-indan-2-ylmethyl)-amino]-cyclohexyl}-5-methyl-1H-benzoimidazol-2-yl)-propan-2-ol. The analysis of the 1H-NMR confirmed the cis-conformation of the cyclohexane. LC-MS showed a single peak, C27H34ClN3O (m/e) calcd 451.2390, obsd 452.3 (M+H). 1H-NMR (CD3OD) □ 7.83 (d, 1H), 7.40 (s, 1H), 7.20 (s, 1H), 7.17 (d, 1H), 7.10 (d, 1H), 7.03 (d, 1H), 5.32 (m, 1H), 3.16 (m, 2H), 2.96 (br s, 1H), 2.73-2.85 (m, 7H), 2.43 (s, 3H), 2.00 (m, 2H), 1.72 (s, 6H), 1.68 (m, 4H).
