실험 절차

A suspension of methyl 3-hydroxy-5-[(1S)-2-methoxy-(1-methylethyl)oxy]benzoate (3.53 g, 14.7 mmol), p-fluoro-phenyl-boronic acid (16.2 mmol), copper(II) acetate (2.94 g, 16.2 mmol), triethylamine (10.3 ml, 73.5 mmol) and freshly activated 4A molecular sieves (17.7 g) in dichloromethane was stirred at ambient temperature and under ambient atmosphere for 2 days. The reaction mixture was filtered, and the dichloromethane was removed in vacuo. The residual oil was partitioned between ethyl acetate and 2 mol/l hydrochloric acid. The ethyl acetate layer was separated, washed with aqueous sodium hydrogen carbonate and brine, dried over Na2SO4 and evaporated to give a residue, which was purified by column chromatograph on silica gel (20-60% ethyl acetate in iso-hexane, gradient) to give the desired ester.
