실험 절차

Method B of the above general procedure was followed using 2-chloroanisole (143 mg, 1.01 mmol) and ethyl cyanoacetate (125 mg, 1.11 mmol). The reaction mixture was purified by column chromatography on silica gel (1:3 dichloromethane/hexanes) to give the desired product (191.4 mg, 87%) as a colorless oil: 1H NMR (CDCl3) δ 7.40-7.35 (m, 2H), 7.03-6.99 (m, 1H), 6.93 (d, 8.0 Hz, 1H), 5.03 (s, 1H), 4.30-4.22 (m, 2H), 3.86 (s, 3H), 1.29 (t, 7.2 Hz, 3H). 13C{1H} NMR (CDCl3) δ 165.19, 156.48, 130.73, 129.44, 121.11, 119.11, 115.92, 111.12, 62.97, 55.72, 38.18, 13.97.
