実験手順
To a solution of tert-butyl 5-chloro-2-fluoro-4-((trans-4-methylcyclohexyl)-methoxy)-benzoate (6.48 g, 18.16 mmol) in toluene-water (40 mL, v/v 20:1) was added cyclopropylboronic acid (2.34 g, 27.26 mmol) and tribasic potassium phosphate (17.37, 81.84 mmol). The reaction mixture was sparged with argon for 10 minutes and then charged with tricyclohexylphosphine tetrafluoroborate (1.35 g, 3.67 mmol) and palladium acetate (0.41 g, 1.82 mmol). The mixture was heated at 110° C. for 72 hours, then cooled to ambient temperature; filtered through a pad of diatomaceous earth and washed with ethyl acetate. The filtrate was concentrated in vacuo, and the residue was purified by column chromatography (0% to 10% ethyl acetate) to give the title compound (5.95 g, 90%): 1H NMR (300 MHz, CDCl3) δ 7.37 (d, J=8.4 Hz, 1H), 6.50 (d, J=12.8 Hz, 1H), 3.78 (d, J=6.1 Hz, 2H), 1.91-1.70 (m, 8H), 1.56 (s, 9H), 1.41-129 (m, 2H), 1.14-0.95 (m, 6H), 0.65-0.60 (m, 2H).
