Procedure

Following general procedure A, methyl hydrogen fumarate (0.39 g, 3.0 mmol) in NMP (8 mL) was reacted with CsHCO3 (0.69 g, 3.6 mmol) and chloroethyl 2-methylpropanoate (0.63 g, 4.2 mmol) to afford 0.65 g (89% yield) of the title compound (42) after isolation and purification. 1H NMR (CDCl3, 400 MHz): δ 6.93 (q, J=5.2 Hz, 1H), 6.88 (d, J=16.0 Hz, 1H), 6.81 (d, J=15.6 Hz, 1H), 3.81 (s, 3H), 2.55 (heptet, J=6.8 Hz, 3H), 1.54 (d, J=5.2 Hz, 3H), 1.18 (d, J=6.8 Hz, 6H). MS (ESI): m/z 245.05 (M+H)+.
