Reaction Steps
To a solution of 5-[2-(2-chloro-4-hydroxy-phenyl)-1-hydroxy-1-trifluoromethyl-propyl]-1-methyl-1H-pyridin-2-one (Example 196, 200 mg) in CH2Cl2 (4 ml) were added 4-fluoro-3-methoxyphenylboronic acid (282 mg), copper-(II)-acetate (307 mg), molecular sieve and pyridine (219 mg). The mixture was stirred at room temperature under an air atmosphere with exclusion of moisture for 7 days. The mixture was filtered, diluted with CH2Cl2 and washed with 1 M aqueous HCl. The organic phase was dried (MgSO4), filtered and concentrated to dryness. The product was purified by chromatography (SiO2, cyclohexane/EtOAc 1:0=>0:1) to give the title compound (139 mg) as an off-white solid. MS (m/e)=486.3 [M+H+].
