Reaction Steps

Trifluoromethanesulfonic acid 3-chloro-4-[2-(2-chloro-pyridin-4-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenyl ester (Example 26, Step 1, 92 mg, 0.2 mmol), (4-methoxycarbonylphenyl)boronic acid (42 mg, 0.3 mmol) and 1,1,bis(diphenylphosphino)-ferrocenpalladium(II)dichloromethane (8 mg, 0.01 mmol) in dioxane (0.6 ml) was treated with water (0.44 ml) and 2N—Na2CO3 (0.3 ml, 0.6 mmol) and stirred at 70° C. under argon for 19 h. The reaction mixture was cooled down to r.t., diluted with ethyl acetate, washed with water and brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by column chromatography (10 g silica gel, heptane/AcOEt 4:1) to give the title compound as a white solid (62 mg). MS (m/e)=484.1 [M+H+].
