실험 절차

A round-bottomed flask was charged with 4-acetamidobenzoyl chloride (0.95 g, 4.57 mmol), anisole (0.60 mL, 5.48 mmoL) and CH2Cl2 (15 mL). Cooled in an ice bath, AlCl3 (0.93 g, 6.85 mmol) was added in portions. The mixture was stirred at 0° C. for 4 h. The resulting dark brown solution was poured into 1 N HCl (25 mL) with ice and the mixture was extracted with EtOAc (2×60 mL). The combined EtOAc extract was washed with water, brine, dried over Na2SO4, filtered, and the filtrate was concentrated to give brown solid. The crude product was purified by chromatography on a silica gel column eluted with hexanes:EtOAc (1:1) to give 0.55 g (45%) of compound 56 as light brown solid. mp 160-162° C. 1H NMR (400 MHz, CDCl3): δ 2.22 (s, 3H), 3.88 (s, 3H), 6.96 (d, J=8.8 Hz, 2H), 7.34 (br s, 1H), 7.55-7.65 (m, 2H), 7.77 (d, J=8.6 Hz, 2H), 7.79 (d, J=8.8 Hz, 2H). LCMS (ESI): m/z 270 (M+H)+, 268 (M−H)−.
