反応手順

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 1M 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+].
