Mode opératoire

20 mL of thionyl chloride was added dropwise to a mixture containing 20.0 g (0.1 mol) of trans-4-pentylcyclohexanecarboxylic acid represented by the following formula (b-i), 0.5 mL of pyridine and 300 mL of toluene in a nitrogen atmosphere, and the mixture was stirred under heating to 80° C. or less for 1 hour. The solvent was distilled off under reduced pressure to provide trans-4-pentylcyclohexanecarboxylic acid chloride.
