반응 단계

A mixture of 2,2,2-trifluoroethyl 4-methylbenzenesulfonate (1.34 g, 5.28 mmol), 2-chloro-5-(hydroxymethyl)phenol (837 mg, 5.28 mmol), K2CO3 (1.46 g, 10.56 mmol) and DMF (9 mL) was heated to 100° C. overnight. It was then poured into ice-water and extracted with ethyl acetate twice. Organic phase washed with water twice, brine and dried with Na2SO4, concentrated to a residue which was purified by flash column chromatograph to give the title compound (903 mg, 75%). 1H NMR (400 MHz, CDCl3): δ 1.77 (1H, t, J=5.6 Hz), 4.42 (2H, q, J=8.0 Hz), 4.68 (2H, d, J=5.2 Hz), 6.99 (1H, dd, J=1.6 Hz, 8.0 Hz), 7.02 (1H, s), 7.37 (1H, d, J=8.0 Hz).
