Versuchsvorschrift

To a solution of 4-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-2,6-dimethyl-benzonitrile (Example 141, step 5, 100 mg) in N,N-dimethylacetamide (1 ml) were added methyl-6-chloro-4-(trifluoromethyl)-nicotinate (75 mg), triethylamine (34 mg) and 1,4-diazabicyclo[2.2.2]octane (4 mg). The mixture was stirred at room temperature for 6 h and then diluted with EtOAc. Water was added. The mixture was extracted with EtOAc. The organic phase was washed with water, dried (MgSO4), filtered and concentrated. The product was purified by chromatography (SiO2, cyclohexane/EtOAc 1:0=>2:3) to give the title compound (132 mg) as a colorless solid. MS (m/e, ISP neg. ion)=585.1 [M−H+].
