Procedure
To a stirred solution of [4-(4-chloro-benzenesulfonyl)-4-(2,5-difluoro-phenyl) -cyclohexylmethanesulfonylamino]-acetic acid tert-butyl ester (Example 20) (80 mg) in dichloromethane (10 mL) was added trifluoroacetic acid (2 mL) and the reaction stirred for 3 hours then evaporated. Purification by column chromatography on silica, eluting with ethyl acetate:dichloromethane:acetic acid (75:25:1), afforded the desired product. MS (ES+) 522 ([MH]+).
