실험 절차

To a solution of 1-(4-bromo-2-fluorophenyl)-2,2,2-trifluoroethanol (1.09 g, 3.99 mmol) in ethyl acetate (30 mL) was added 2-iodoxybenzoic acid (2.28 g, 7.97 mmol). The reaction was heated to reflux overnight. The reaction was cooled to room temperature and diluted with heptanes (30 mL). The mixture was filtered through Celite and the filtrate was concentrated to give the title compound (1.03 g, 95%) as a pale yellow oil. 1H NMR (400 MHz, CDCl3, δ): 7.44 (dd, J=10.15, 1.56 Hz, 1H), 7.48 (m, 1H), 7.76 (m, 1H).
