Versuchsvorschrift

0.771 g (3.6 mmol) of (-)-menthoxyacetic acid is stirred under reflux with 2.1 g of thionyl chloride for 4 to 5 h. The thionyl chloride is first removed from the solution by distillation under reduced pressure. 3 ml of dry benzene are then added in order to remove residual thionyl chloride by means of vacuum distillation. 0.9 g of the title compound is obtained.
