To a stirring solution of ethyl 3-{3-chloro-5-(methyloxy)-4-[((1S)-1-{6-[4-(trifluoromethyl)phenyl]-2-pyridinyl}pentyl)oxy]phenyl}propanoate (118 mg, 0.20 mmol) in THF (3 mL) and MeOH (3 mL) at ambient temperature was added NaOH (2N, 3 mL) and the mixture stirred for 2 h and then left to stand overnight. HCl (2N, 3 mL) was then added and the mixture reduced under vacuum. The residue was then purified by SPE (silica, 5 g cartridge) with a pad of celite on the top, eluting with cyclohexane:EtOAc (gradient 20:1 to 0:1) to give the title compound (94 mg).
