실험 절차
4-Hydroxybenzoic acid (1.1 g, 7.96 mmoL) and aniline (742 mg, 7.23 mmol) were dissolved in 20 mL of dry DMF. To the above solution EDCl (1.53 g, 7.23 mmol) was added in one portion and the resulting mixture was stirred at rt overnight under nitrogen. The reaction mixture was then partitioned between EtOAc (200 mL) and water (200 mL). The organic layer was separated, washed consecutively with 1 N HCl, water, saturated sodium bicarbonate solution, water, and brine, and dried over MgSO4. Solvent was removed under reduced pressure and the crude product was purified by column chromatography using 10% EtOAc in hexane to give 450 mg (29% yield) of 4-Hydroxy-N-phenyl-benzamide. MS (ES) m/z: 214.08 (M+1).
