Procedure

NaOH (108 mg, 2.7 mmol) was added to trans-{4-[4-(3-{[2-(2-chlorophenyl)-5-trifluoromethyloxazole-4-carbonyl]amino}propionylamino)phenyl]cyclohexyl}acetic acid methyl ester (160 mg, 0.27 mmol) dissolved in THF/MeOH/water (25 mL, 3:2:1). The reaction mixture was stirred at 25° C. for 5 hours and concentrated under vacuum. The residue was acidified with 1M HCl up to pH of 2 and extracted with ethyl acetate. The extract was washed with brine and dried with anhydrous sodium sulfate and concentrated under vacuum. Acetonitrile was added thereto and cooled to obtain a filtrate, and the filtrate was filtered and separated to obtain the desired compound (130 mg, 83%) as a white solid.
