Reaction Steps

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 (2 ml) were added methyl-6-chloro-nicotinate (68 mg) and cesium carbonate (256 mg). The mixture was stirred at room temperature for 3 h. Methyl-6-chloro-nicotinate (23 mg) was added and the mixture was stirred overnight 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 (103 mg) as a colorless solid. MS (m/e)=519.2 [M+H+].
