Versuchsvorschrift

Added to 284 g (being 2 mol) of 4-methyl-3-cyclohexenylmethanol and one liter toluene solution containing 100 g (being 1 mol) of succinic acid anhydrate, was 5 g of toluenesulfonic acid monohydrate, and allowed to react for 8 hours at 110–120° C., while any generated water was removed using a water separating apparatus. After the reacted solution was washed with sodium bicarbonate water, distillation under reduced pressure was conducted to remove any toluene. The residual crude product was distilled under reduced pressure to obtain the objective compound. The yield was 90%.
