실험 절차

An excess of thionyl chloride was added to 10 g of 4-isopropyl-1-methylcyclohexylcarboxylic acid (cis:trans=1:1, b.p.=122° C./2 mm Hg), and the mixture was stirred for 3 hours. The remaining thionyl chloride was distilled off in a vacuum from the resulting reaction mixture, and the oily product obtained was distilled in a vacuum to obtain 9.5 g of 4-isopropyl-1-methylcyclohexylcarbonyl chloride having a boiling point of 150° to 152° C./60 mm Hg. (Yield: 86.4%.)
