実験手順
Following general procedure A, methyl hydrogen fumarate (0.42 g, 3.3 mmol) in NMP (6 mL) was reacted with CsHCO3 (0.69 g, 3.6 mmol) and chloroethyl benzoate (0.55 g, 3.0 mmol) to afford 0.2 g (24% yield) of the title compound (43) after purification by silica gel flash column chromatography (Biotage) using a mixture of ethyl acetate (EtOAc) and hexanes (1:8) as eluent. 1H NMR (CDCl3, 400 MHz): δ 8.08-8.02 (m, 2H), 7.63-7.56 (m, 1H), 7.49-7.42 (m, 2H), 7.21 (q, J=5.2 Hz, 1H), 6.92 (d, J=16.0 Hz, 1H), 6.85 (d, J=16.0 Hz, 1H), 3.81 (s, 3H), 1.69 (d, J=5.2 Hz, 3H). MS (ESI): m/z 278.99 (M+H)+.
