Procedure
A solution of (4-amino-piperidin-1-yl)-[(4S,5R)-2-(6-tert-butyl-4-ethoxy-pyridin-3-yl)-4,5-bis-(4-chloro-phenyl)-4,5-dimethyl-4,5-dihydro-imidazol-1-yl]-methanone (87 mg, 0.139 mmole, example 204) in dichloromethane (5 mL) was treated with methanesulfonyl chloride (31.8 mg, 0.277 mmole, Aldrich) at 0° C. and allowed to stir for 1 h before diluted with dichloromethane (60 mL), washed with aqueous sodium carbonate (15 mL), water (15 mL) and concentrated. The residue was purified by flash column chromatography (silica gel, eluting with a gradient of 1% to 10% methanol in dichloromethane) to give the title compound (83.8 mg). HR-MS (ES, m/z) calculated for C35H44Cl2N5O4S [(M+H)+] 700.2486, observed 700.2482.
