Participants

Reaction Steps

Trans-[4-(4-{3-[(biphenyl-4-carbonyl)amino]propionylamino}phenyl)cyclohexyl]acetic acid methyl ester (60 mg, 0.120 mmol) was put into THF/water (20 mL, 3:1) solvent, and NaOH (38.51 mg, 0.963 mmol) was added thereto. The mixture was stirred for 24 hours, THF was removed, and pH of the mixture was adjusted to be 2-3 with 1N hydrochloric acid. The reaction mixture was extracted with EtOAC (3×100 mL), washed with brine and dried with anhydrous sodium sulfate, and the solvent was removed. The obtained crude material was crystallized with acetonitrile to obtain the desired compound (56 mg, 96%) as a white solid.
