Procedure

5′-Amino-N-(cyclopropylmethyl)-2′-methyl-1,1′-biphenyl-4-carboxamide (48 mg, 0.17 mmol), 3-fur-3-ylbenzoic acid (32 mg, 0.17 mmol), HATU (65 mg, 0.17 mmol), HOBT (23 mg, 0.17 mmol) and DIPEA (88 μl) were stirred in DMF (1.5 ml) for 18 h at room temperature. The reaction was partitioned between ethyl acetate (100 ml) and hydrochloric acid (0.5M, 20 ml), the organic phase washed with aqueous sodium hydrogen carbonate (saturated) and dried (magnesium sulphate). The solvent was evaporated under vacuum to give N-(4′-{[(cyclopropylmethyl)amino]carbonyl}-6-methyl-1,1′-biphenyl-3-yl)-3-fur-3-ylbenzamide (61 mg, 79%).
