To a solution of 1-methyl-1H-imidazole-4-sulfonic acid {2-[3-(3-benzyl-pyrrolidin-3-yl)phenoxy]-ethyl}-amide (example 61, 59 mg, 0.13 mmol) in dichloromethane under nitrogen was added acetone (8 mg, 0.14 mmol), two drops acetic acid, 2 mg Na2SO4, sodium triacetoxyborohydride. The mixture was stirred over night at room temperature. Saturated NaHCO3-solution was added and the mixture was extracted with dichloromethane. The organic layer was washed with water, dried over Na2SO4 and the solvent evaporated affording 54 mg of colorless oil. Purification on 4 g Si % with dichloromethane+5% MeOH to 10% MeOH afforded 4 mg of product.
