Versuchsvorschrift

NaOH (71.9 mg, 1.8 mmol) was added to trans-[4-(4-{3-[(1-phenyl-3-trifluoromethyl-1H-pyrazole-4-carbonyl)amino]propionylamino}phenyl)cyclohexyl]acetic acid methyl ester (100 mg, 0.18 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 (95 mg, 98%) as a white solid.
