反応手順
To a cold solution of 4-(trifluoromethyl)benzonitrile (0.500 g, 2.92 mmol) in DMSO (6.0 mL) was added H2O2 (50%) (5 mL) at 0° C., followed by portion-wise addition of K2CO3 (0.121 g, 0.87 mmol). The reaction mass was allowed to attain RT and stirred for 1 h. The reaction mass was quenched in ice water and extracted with DCM and concentrated to afford 0.300 g of product. 1H NMR (400 MHz, DMSO d6): δ 7.60 (br s, 1H), 7.82 (d, J=7.5 Hz, 2H), 8.05 (d, J=6.6 Hz, 2H), 8.17 (br s, 1H); MS (m/z): 190.11 (M+H+).
