Procedure

4-{[(4-Benzofuran-2-yl-phenylcarbamoyl)-(4-tert-butyl-phenyl)-methyl]-methyl-amino}-benzoic acid (110 mg, 0.2 mmol), was taken up in 3 mL of DMF followed by addition of HOBt (79 mg, 0.52 mmol) and EDCI (99 mg, 0.52 mmol). The reaction was stirred at RT for 30 min, taurine (103 mg, 0.083 mmol) was added followed by Hunig's base (107 mg, 0.083 mmol) and allowed to stir an additional 16 h at RT. The solution was filtered through a fit and the DMF was subjected to reverse phase HPLC purification. After removal acetonitrile/water under reduced pressure, followed by trituration with methanol, gave a white solid (50 mg, 39%).
