実験手順: A mixture of methyl 4-bromo-3-(methoxymethyl)benzoate (Intermediate 1, Step 2, 5.00 g, 19.3 mmol), 3-fluoro-2-methylphenylboronic acid (4.46 g, 29.0 mmol), bis(triphenylphosphine)palladium(II) chloride (271 mg, 0.39 mmol) and cesium fluoride (8.79 g, 57.9 mmol) was prepared in dioxane (50 mL) and water (20 mL) under nitrogen atmosphere. The reaction mixture was heated at 100° C. for 1 hour. The reaction mixture was cooled at RT, diluted with MTBE (250 mL) and the layers were separated. The organic layer was washed with water (100 mL) and brine (100 mL). The aqueous layers were extracted with MTBE (150 mL). The organic layers were combined, dried over MgSO4 and concentrated under reduced pressure. After purification by flash chromatography (silica, EtOAc/n-hexane), the title compound was obtained as a colorless oil (4.85 g, 87%). HPLC (Method A), Rt 5.0 min (purity: 99.5%). LC/MS (Method B): 289.0 (M+H)+. The reaction mixture was cooled at RT the layers were separated The organic layer was washed with water (100 mL) and brine (100 mL) The aqueous layers were extracted with MTBE (150 mL) dried over MgSO4 concentrated under reduced pressure After purification by flash chromatography (silica, EtOAc/n-hexane)
