실험 절차
4-cyanobenzoyl chloride (2 g, 12.08 mmol), DIEA (7.3 mL, 42 mmol), and 4-tert-butylaniline (1.9 mL, 11.9 mmol) were stirred in tetrahydrofuran (50 mL) overnight at room temperature. The tetrahydrofuran was removed under reduced pressure and replaced with ethyl acetate. The ethyl acetate was washed with H2O and brine, dried over Na2SO4, filtered, and the filtrate concentrated under reduced pressure. The residue was purified by column chromatography on silica gel (eluant gradient from 8:2 hexanes:ethyl acetate to 1:1 hexanes:ethyl acetate) to afford the title compound as a solid. 1H NMR (300 MHz, DMSO-d6) δ 10.41 (s, 1H), 8.08–8.12 (m, 2H), 8.01–8.04 (m, 2H), 7.66–7.69 (m, 2H), 7.37–7.41 (m, 2H), 1.28 (s, 9H); MS (ESI+) m/z 279 (M+H)+.
