실험 절차

To a solution of (2R,3R,4R,5S,6S)-2-(acetoxymethyl)-6-(3-bromo-5-(4-ethylbenzyl)-4-methylphenyl)-tetrahydro-2H-pyran-3,4,5-triyl triacetate (131) (WO2008/101939, Example V) (500 mg, 0.807 mmole) in toluene (6 mL) and water (3 mL) were added 4-methoxyphenylboronic acid (147 mg, 0.969 mmole), Pd(OAc)2 (18.1 mg, 0.0807 mmole), tricyclohexylphosphonium tetrafluoroborate (59.4 mg, 0.161 mmole), and K3PO4 (685 mg, 3.23 mmole). The mixture was stirred at 100° C. overnight. After cooling to ambient temperature, the mixture was diluted with water and extracted with ethyl acetate. The organic layer was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The crude residue was purified by silica gel chromatography to yield the title compound (484 mg, 0.748 mmole, 93%) as a yellow solid.
