Vorschrift

In 80 ml of toluene were dissolved 16.8 g of 1-(2-tetrahydrofuranyl)cyclopentanol, 13.1 g of triethylamine, and 0.5 g of 4-(N,N-dimethylamino)pyridine. Then 10.7 g of acrylic chloride was added to the solution at 50° C., which was stirred at the temperature for one hour. Water, 50 ml, was added to the solution below 30° C., followed by ordinary post-treatment. Vacuum distillation yielded 18.1 g of 1-(2-tetrahydrofuranyl)cyclopentyl acrylate. The two-step yield was 80%.
