Versuchsvorschrift

{1-[(4S,5R)-2-(6-tert-Butyl-4-ethoxy-pyridin-3-yl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl]-piperidin-4-yl}-acetic acid methyl ester (519 mg, 0.763 mmole, example 162) in methanol (4 mL) and tetrahydrofuran (4 mL) was treated with lithium hydroxide (36 mg) in water (4 mL) and allowed to stir at room temp. for 3 h. The mixture was neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The organic extracts were washed with brine, dried over anhydrous sodium sulfate. The solids were filtered off, and the filtrate was concentrated to give {1-[(4S,5R)-2-(6-tert-butyl-4-ethoxy-pyridin-3-yl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazole-1-carbonyl]-piperidin-4-yl}-acetic acid (482 mg) which was used without purification.
