Participants

Reaction Steps

To a mixture of 4-(3-(cyclopropylmethyl)ureido)benzoic acid (2.134 mmol, 0.5 g), 2-(4-((1,4-diazepan-1-yl)methyl)phenyl)-1,1,1,3,3,3-hexafluoropropan-2-ol (2.134 mmol, 0.761 g) and triethylamine (5.34 mmol, 0.744 mL, 0.540 g) in dichloromethane (30 mL) was added N-(3-dimethylaminopropyl)-N′-ethylcarbodiimide hydrochloride (2.56 mmol, 0.491 g). The reaction was stirred for 24 hours then was chromatographed on silica eluting with dichloromethane to dichloromethane/methanol (6%) then re-chromatographed on silica eluting with ethyl acetate to ethyl acetate/methanol (2%) to give the title compound (780 mg). MS (ESI) m/z 573.0 [M+H]+
