Versuchsvorschrift

Trifluoro-methanesulfonic acid 3-chloro-4-[2-(2-chloro-pyridin-4-yl)-3,3,3-trifluoro-2-hydroxy-1-methyl-propyl]-phenyl ester (Example 135-Step 1, 1.0 g) and piperidine-4-carboxylic acid ethyl ester (0.773 mL) in 1-methyl-2-pyrrolidon (10 mL) were heated at 220° C. in a microwave oven for 30 minutes. The reaction mixture was then diluted with water (100 mL), extracted twice with ethyl acetate. The combined organic phases were washed with brine, dried over MgSO4 and concentrated in vacuo. The residue was purified by flash chromatography (70 g silica gel, heptane/acetic acid isopropylester 80/20 to 70/30) to give the title compound as light yellow viscous oil (119 mg). MS (m/e)=619.2 (MH+).
