Procedure

To a solution of (4-tert-butyl-phenoxy)acetic acid (125 mg, 0.6 mmol), 3-amino benzamide (163.5 mg, 1.2 mmol), HOBT (162 mg, 1.2 mmol) and DIPEA (155 mg, 1.2 mmol) in DMF (6 ml) was added EDC (230.05 mg, 1.2 mmol) at room temperature and the resulting mixture was stirred until reaction completion as indicated by TLC. Reaction mixture was poured onto ice cold water, diluted with a mix of MeOH:MC (10%), separated organic layer and sequentially washed with aqueous sodium bicarbonate, brine and water, and dried over anhydrous MgSO4. The solvent was filtered and evaporated under reduced pressure to afford a crude solid, which was purified flash chromatography on silica gel (MeOH:MC=1:9˜2:8) to afford of 3-[2-(4-tert-butyl-phenoxy)-acetylamino]-benzamide as a colorless solid (168 mg, 85.75% yield).
