5-(4-Chlorophenyl)-2-furoic acid → HCID 69203690, compound

Participants

Reaction Steps

5′-Amino-N-(cyclopropylmethyl)-2′-methyl-1,1′-biphenyl-4-carboxamide (53 mg, 0.189 mmol) and 5-(4-chlorophenyl)-2-furoic acid (84.2 mg, 0.378 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 dissolved in methanol, filtered through an SCX SPE and the solvent evaporated under vacuum to give 5-(4-chlorophenyl)-N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-2- furamide (10 mg, 11%).
