Versuchsvorschrift

3-Chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(2-methyl-pyridin-4-yl)-propyl]-phenol (100 mg, obtained in Example 93, step 6) and ethyl-4-(bromomethyl)-pyridine-2-carboxylate (85 mg, [CAS Reg. No. 153994-03-7]) were dissolved in DMF (5 mL) followed by addition of silver carbonate (80 mg). The mixture was heated to 80° C. for 3 hours. The reaction mixture was cooled, poured into ice/water and extracted two times with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4, filtered and the solvent was evaporated. The residue was purified by flash chromatography (silica gel, gradient of heptane in ethyl acetate) to give the title compound as a yellow foam (98 mg, 63%). MS (m/e)=509.3 [MH+].
