Procedure

To a solution of the title compound of Example 48 (the slower moving enantiomer), (−)4-(3-chloro-phenyl)-6-[(6-chloro-pyridin-3-yl)-(4-methoxy-benzyl-amino)-(3-methyl-3H-imidazol-4-yl)-methyl]-1-cyclopropylmethyl-1H-quinolin-2-one (1.07 g, 1.64 mmol) in dichloromethane (6.5 ml) was added trifluoroacetic acid (TFA, 6.5 ml) slowly at 0° C. The reaction mixture was stirred at ambient temperature for 80 minutes after which time it was diluted with DCM (10 ml) and was poured into a chilled aqueous solution of potassium carbonate. After separation, the organic layer was washed with brine, dried over MgSO4 and concentrated under vacuum to give the crude product. It was chromatographed on silica gel with MeOH—CHCl3—NH4OH (1.5:98.5:0.15) as the eluents to afford the title compound as a white solid (0.588 g, 1.11 mmol, 68% yield). It is the faster eluting enantiomer of 6-[amino-(6-chloro-pyridin-3-yl)-(3-methyl-3H-imidazol-4-yl)-methyl]-4-(3-chloro-phenyl)-1-cyclopropylmethyl-1H-quinolin-2-one with >99% optical purity.
