Procedure
In analogy to Example 49, 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) was reacted with 3-ethoxycarbonylphenylboronic acid at 70° C. 4 h to give the title compound as a colorless white solid. MS (m/e)=498.1 [M+H+].
