Procedure
To a methylene chloride suspension of aluminum chloride, a methylene chloride solution of (R)-3-(3-methoxyphenyl)butyric acid chloride was added dropwise under ice cooling. After stirring at the same temperature for 15 minutes, a methylene chloride solution of trans-4-propylcyclohexylbenzene was added dropwise. After the completion of the reaction, the reaction system was added to iced water and the organic layer was separated by adding methylene chloride. The organic layer was washed twice with water and then washed with saturated brine. The aqueous layer was washed with methylene chloride and, after combining the organic layer, the solvent was concentrated to obtain a crude product of (R)-1-(4-cyclohexylphenyl)-3-(3-methoxyphenyl)-butan-1-one. The resulting crude product was purified by column chromatography and recrystallized from ethanol to obtain (R)-1-(4-cyclohexylphenyl)-3-(3-methoxyphenyl)-butan-1-one (R-isomer of the compound represented by the formula (XI-c)).
