실험 절차
A solution of N-(4-Acetyl-2-bromo-phenyl)-acetamide (10.0 g, 39.05 mmol) in concentrated hydrochloric acid (200 mL) was stirred for 5 h under reflux. The reaction mixture was concentrated under reduced pressure. The residue was treated with a saturated aqueous solution of NaHCO3 (75 mL), extracted with CH2Cl2 (2×70 mL) and dried over Na2SO4. Evaporation leads to the product (8.35 g, 100%) which was used in step 2 without further purification.
