Reaction Steps

To a solution of 6-{3-chloro-4-[3,3,3-trifluoro-2-hydroxy-1-methyl-2-(1-methyl-6-oxo-1,6-dihydro-pyridin-3-yl)-propyl]-phenoxy}-4-trifluoromethyl-nicotinic acid methyl ester (Example 163, 65 mg) in tetrahydrofuran (0.5 ml) was added a 1 M aqueous sodium hydroxide solution (0.23 ml) at 0° C. The mixture was stirred at 0° C. for 30 min and at room temperature for 3 h. The mixture was cooled in an ice bath. 2 M aqueous HCl (0.12 ml) and EtOAc were added. The organic phase was dried (MgSO4), filtered and concentrated. The product was purified by chromatography (SiO2, cyclohexane/EtOAc 1:1=>EtOAc=>EtOAc/MeOH 4:1) to give the title compound (61 mg) as a colorless solid. MS (m/e)=551.3 [M+H+].
