4'-Trifluoromethyl-biphenyl-3-carboxylic acid → HCID 69202928, compound

Participants

Reaction Steps

5′-Amino-N-(cyclopropylmethyl)-2′-methyl-1,1′-biphenyl-4-carboxamide (53 mg, 0.189 mmol) and 3-(4-trifluoromethylphenyl)benzoic acid (151 mg, 0.57 mmol) were mixed in THF (5 ml) and the mixture shaken in a varian tube for 15 min at room temperature. Carbodiimde resin (500 mg) was added and shaking continued for 18 h. The solution was filtered off and concentrated under vacuum. The residue was chromatographed on a silica gel flash column eluting with ethyl acetate/hexane (1:1) and the solvent evaporated under vacuum to give N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-3-(4-trifluoromethylphenyl)benzamide (67 mg, 67%).
