実験手順

Trifluoromethanesulfonic acid 3-chloro-4-[2-(4-ethyl-3-oxo-3,4-dihydro-2H-benzo[1,4]oxazin-6-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenyl ester (150 mg, 0.27 mmol), 3-chloro-4-(methoxycarbonyl)phenylboronic acid (86 mg, 0.4 mmol) and 1,1, bis(diphenylphosphino)-ferrocenpalladium(II)dichloromethane (11 mg, 0.05% mol) in dioxane (0.8 ml) was treated with water (0.6 ml) and 1M-Na2CO3 (0.4 ml, 0.4 mmol) and stirred at 70° C. under argon for 6.5 h. The reaction mixture was cooled down to r.t., diluted with ethyl acetate, washed with water and brine, dried over MgSO4 and concentrated under vacuum. The residue was purified by column chromatography (10 g silica gel, heptane/AcOEt 4:1) to give the title compound (112 mg) as a white solid. MS (m/e)=582.3 [M+H+]
