실험 절차

A solution of 3-iodoaniline (5.0 g, 23 mmol), α-acetyl-γ-butyrolactone (14.6 g, 0.11 mol) in ethanol (100 mL) was heated under reflux for seven days. The mixture was evaporated, and the residue was purified by silica gel column chromatography (10% ethyl acetate/hexane), to give the title compound (7.54 g) as white crystals.
