Procedure

To a stirred solution of 5-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1,3-dimethyl-1H-pyridin-2-one (Example 203, step 5, 80 mg) in N,N-dimethylacetamide (1.5 ml) were added 4-fluoro-2-(trifluormethyl)benzaldehyde (63 mg) and cesium carbonate (208 mg). The mixture was stirred at room temperature for 3 h. Water was added and the mixture was extracted with ethyl acetate. The organic phase was dried (MgSO4), filtered and concentrated. The product was purified by chromatography (SiO2, cyclohexane/EtOAc 1:0=>0:1) to give the title compound (111 mg) as an off-white solid. MS (m/e)=548.2 [M+H+].
