Reaction Steps
To diethylether (250 mL) was added magnesium (6.04 g) and a catalytic amount of iodine and the mixture was stirred and thereto was gradually added dropwise 2-chlorobenzyl chloride (20.0 g). After stirring for 1 hour from the time when the temperature of such mixture began to rise, thereto was added a solution of 4-chlorobenzonitrile (18.8 g) in tetrahydrofuran/diethylether (20 mL/50 mL) and the mixture was stirred for 3 hours. To the reaction mixture was added 2N HCl (150 mL) under ice-cooling and the mixture was stirred at room temperature for 2 hours. The reaction mixture was extracted with ethyl acetate and the organic layer was washed with 1N HCl, water and saturated brine, dried over magnesium sulfate and filtered. The filtrate was concentrated in vacuo and the resultant crude product was purified by column chromatography on silica gel (solvent: hexane/ethyl acetate=40/1 to 20/1) to obtain 2-(chlorobenzyl)(4-chlorophenyl)methanone (24.40 g; yield: 74%) as a powder.
