실험 절차

To 2-bromo-4-ethylsulfanyl-1-fluorobenzene (2.2 g, 9.36 mmol) in DCM (20 mL) was added m-CPBA (6.47 g, 37.4 mmol). The mixture was stirred at room temperature for 12 h. Aqueous saturated Na2S2O3 (100 mL) was added, and extractive work up with CH2Cl2 gave the title compound (1.5 g, 50%) as a yellow solid which was carried on without purification. 1H NMR (CDCl3, 400 MHz) δ 8.15 (dd, J1=6.4 Hz, J2=2.4 Hz, 1H), 7.88-7.85 (m, 1H), 7.32 (t, J=8.4 Hz, 1H), 3.14 (q, J=7.2 Hz, 2H), 1.31 (t, J=7.6 Hz, 3H).
