To a suspension of 4′-cyano-6-methyl-biphenyl-3-carboxylic acid 3 (40 mg, 0.17 mmol) in anhydrous methylene chloride (5 ml) is added 2 drops of DMF. Then oxalyl chloride (32 mg, 22 μl, 0.25 mmol) is added. The mixture is stirred at ambient temperature until it turns clear. After that, it is concentrated, re-dissolved in anhydrous methylene chloride (3 ml), and added to a solution of 4-(morpholine-4-sulfonyl)-phenylamine (61 mg, 0.25 mmol) and triethylamine (34 mg, 47 t, 0.33 mmol) in methylene chloride (2 ml). The mixture is stirred for 2 hours, concentrated and the residue is purified by preparative mass triggered HPLC (C1-8 column, eluted with CH3CN—H2O containing 0.05% TFA) to give 4′-cyano-6-methyl-biphenyl-3-carboxylic acid [4-(morpholine-4-sulfonyl)-phenyl]-amide: 1H NMR (DMSO-d6) δ 10.64 (s, 1 H), 8.07 (d, 2 H, J=8.8 Hz), 7.97 (d, 2 H, J=8.4 Hz), 7.95 (d, 1 H, J=8.8 Hz), 7.89 (s, 1 H), 7.43 (d, 2 H, J=8.4 Hz), 7.67 (d, 2 H, J=8.8 Hz), 7.53 (d, 2 H, J=8.8 Hz), 3.63 (m, 4 H), 2.84 (m, 4 H) 2.32 (s, 3 H); LC-MS m/z: 462.1 (M+1).
