실험 절차
The pure ester was dissolved in 60 ml of CH2Cl2 was added 6 drops of anisole and 60 ml of CF3CO2H and the solution was atirred at rt for 16 hr. Upon removal of volatiles, the residue was dried three times by dissolving in toluene to afford 20.02 g of the title compound. 1H-NMR (CDCl3): δ 2.35 (s, 3H), 3.67 (s, 2H), 6.92-6.95 (m, 2H), 7.19 (d of d, 1H, J=8.2, 5.7 Hz) ppm.
