Procedure

A mixture of 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]-piperidine-4-carboxylic acid methyl ester (575 mg, 0.864 mmole, example 210) and lithium hydroxide hydrate (217 mg, 5.179 mmole) in water (20 mL) and tetrahydrofuran (20 mL) was stirred at room temperature for 4 h before neutralized with 1N hydrochloric acid and extracted with ethyl acetate. The organic extracts were washed with brine and dried over sodium sulfate and concentrated to give the title compound (552.5 mg, 98%). HR-MS (ES, m/z) calculated for C35H41Cl2N4O4 [(M+H)+] 651.2500, observed 651.2498.
