1-Hydroxybenzotriazole → N-(4'-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1'-biphenyl-3-yl)-5-(3-chlorophenyl)-2-furamide

Participants

Reaction Steps

5′-Amino-N-(cyclopropylmethyl)-2′-methyl-1,1′-biphenyl-4-carboxamide (24 mg, 0.085 mmol), 5-(3-chlorophenyl)-2-furoic acid (9.5 mg, 0.043 mmol), 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (16 mg, 0.085 mmol), HOBT (12 mg, 0.085 mmol) and DIPEA (15 μl, 0.085 mmol) in DMF (4 ml) were stirred at room temperature for 4 h. The DMF was evaporated under vacuum and the residue partitioned between ethyl acetate and water. The organic fraction was concentrated under vacuum and the residue purfied by preparative HPLC to give N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-5-(3-chlorophenyl)-2-furamide (20 mg, 95%). NMR; δH [2H6]—DMSO 10.25,(1H, s), 8.64,(1H, t), 8.11,(1H, t), 7.96-7.94,(3H, m), 7.75,(1H, dd), 7.66,(1H, d), 7.52,(1H, t), 7.49-7.44,(3H, m), 7.39,(1H, d), 7.34-7.31,(2H, m), 3.18,(2H, t), 2.23,(3H, s), 1.06,(1H, m), 0.45,(2H, m), 0.26,(2H, m). LCMS: retention time 3.88 min, MH+485.
