실험 절차
To a solution of (3,5-diethoxy-4-fluoro-phenyl)-methanol (2.30 g, 10.7 mmol, 1.0 equiv) in 1,2-dichloroethane (50 mL) was added activated MnO2 (2.89 g, 33.3 mmol, 3.1 equiv). The reaction mixture was stirred for 21 h at 50° C. and then filtered through Hyflo Super Cel providing after evaporation of the solvent under reduced pressure 1.90 g (83%) of the title compound. 1H NMR (400 MHz, CDCl3): δ 1.38 (t, J=7.0 Hz, 6H), 4.09 (q, J=7.0 Hz, 4H), 7.04 (d, J=7.2 Hz, 2H), 9.75 (s, 1H). MS (EI): 212.1 [M]+.
