実験手順

Trans-[4-(4-aminophenyl)cyclohexyl]acetic acid methyl ester (150 mg, 0.6 mmol), EDCI (290.7 mg, 1.5 mmol), 3-[(2-phenyl-5-trifluoromethyloxazole-4-carbonyl)amino]propionic acid (228.9 mg, 0.7 mmol), HOBt (123 mg, 0.91 mmol) and ethyldiisopropylamine (275 mg, 0.21 mmol) dissolved in dichloromethane (15 mL) were stirred for 24 hours. The reaction mixture was diluted with aqueous NaHCO3 and extracted with dichloromethane. The extract was washed with brine and dried with anhydrous sodium sulfate and concentrated under vacuum. The residue was purified by silica gel column chromatography to obtain the desired compound (330 mg, 98%) as a white solid.
