Versuchsvorschrift

This compound was prepared from 3-isopropyl phenylmagnesium bromide and 16a according to the procedure described in example 16. To a solution of 3-hydroxy-2,2-dimethylpropanoic acid (0.14 mmol), DIEA (1.7 mmol) and HATU (0.14 mmol) in DMF was added 1-(8-{2-[4(-3-isopropylphenyl)piperdin-4-yl]ethyl}-8-azabicyclo[3.2.1]oct-3-yl)-2-methyl-1H-benzimidazole hydrochloride (0.13 mmol) in the same solvent and stirring was continued overnight. The reaction mixture was diluted with EtOAc, and washed with NaHCO3, water, and satd. brine and dried (Na2SO4). The solvent was removed in-vacuo and the crude material was purified by HPLC to 1 as a clear film. H NMR (400 MHz, CDCl3) 9.72 (s, 2H), 8.48 (s, 1H), 7.64 (d, 1H), 7.04-7.36 (m, 8H), 4.74 (t, 1H), 3.19-3.32 (m, 4H), 2.88-2.97 (m, 3H), 2.60 (s, 3H), 2.43-2.47 (d, 4H), 2.37 (s, 2H), 1.86-2.33 (m, 10H), 1.77 (d, 2H), 1.26-1.28 (d, 6H). LCMS m/z (M+H) calc: 556.79, obsd: 557.79.
