実験手順
Using general procedure A, benzamide (150 mg, 1.24 mmol) was coupled with N,N-dimethyl-2-iodoaniline (160 μL, 1.05 mmol). The crude product was purified by flash chromatography on silica gel (2×15 cm; hexane-ethyl acetate 7:1; 15 mL fractions). Fractions 8–15 provided 239 mg (95% yield) of the product as a pale yellow oil. 1H NMR (400 MHz, CDCl3): δ 9.42 (br s, 1H), 8.57 (dd, J=7.8, 1.4 Hz, 1H), 7.98–7.92 (m, 2H), 7.62–7.51 (m, 3H), 7.26 (dd, J=7.8, 1.4 Hz, 1H), 7.22 (td, J=7.8, 1.4 Hz, 1H), 7.12 (td, J=7.8, 1.4 Hz, 1H), 2.74 (s, 6H).
