Reaction Steps

A mixture of methyl 2-(bromomethyl)-5-chlorobenzoate (step 1, 300 mg, 1.14 mmol) and tetrakis(triphenylphosphine)palladium (0) (132 mg, 0.11 mmol) in 1,2-dimethoxyethane (6 mL) was stirred at 50° C. under nitrogen for 30 min. Then 3-fluorophenylboronic acid (191 mg, 1.37 mmol) and 2 M sodium carbonate solution (2.28 mL, 4.55 mmol) was added, and the resulting mixture was heated at 90° C. under nitrogen for 16 h. After cooling to room temperature, the mixture was diluted with ethyl acetate (50 mL) and washed with 1 M hydrochloric acid (30 mL), saturated sodium hydrogen carbonate aqueous (30 mL), and brine (30 mL). The organic layer was dried over magnesium sulfate, and evaporated in vacuo. The residue was purified by TLC [hexane/ethyl acetate (8:1)] to give 107 mg (34%) of the title compound as colorless oil: 1H-NMR (CDCl3) δ 7.91 (1H, d, J=2.4 Hz), 7.41 (1H, dd, J=8.4, 2.4 Hz), 7.26–7.14 (2H, m), 6.91–6.79 (3H, m), 4.34 (2H, s), 3.84 (3H, s).
