Participants

Reaction Conditions

Reaction Steps

Charged methyl 4-bromo-2-ethylbenzoate (1.9 g, 7.85 mmol), Zn(CN)2 (1.48 g, 12.56 mmol), Pd(PPh3)4 (1.0 g, 0.94 mmol) and DMF (30 mL) to a flask, the system was then purged with nitrogen and heated at 100° C. for 6 h. The reaction mixture was then filtered. The filtrate was extracted with ethyl acetate and concentrated the organic phase for flash column chromatograph to give 0.6 g of the title compound (40%). 1H NMR (400 MHz, CDCl3): δ 1.24 (3H, t, J=7.6 Hz), 2.99 (2H, q, J=7.6 Hz), 3.92 (3H, s), 7.52-7.54 (1H, m), 7.57 (1H, s), 7.90 (1H, d, J=8.0 Hz).
