Reaction Conditions

Reaction Steps

To a mixed solution of acetonitrile (3.54 mL) and THF (30 mL) was added dropwise a solution of n-butyllithium in hexane (1.6 M, 42.1 ml), and the mixture was stirred at −78° C. for 30 min. To the reaction mixture was added dropwise a solution of 1-(3,4-dichlorophenyl)-2-(4-methoxyphenoxy)ethanone (14 g) in THF (45 mL), and the mixture was stirred at −78° C. for 10 min, and then stirred for 1 hr while warming to room temperature. The reaction mixture was diluted with water, and the mixture was extracted with ethyl acetate. The obtained extract was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/hexane) to give the title compound (11.73 g).
