0.1 g of p-toluenesulphonic acid was added to 4.26 g (0.02 mol) of 2-(2-fluorobenzyloxy)-butane-1,4-diol and the mixture was slowly heated to 200° C. under a waterpump vacuum. A mixture of water of reaction and 3-(2-fluorobenzyloxy)-tetrahydrofurane was obtained in the distillate. After fractional distillation, 3.8 g (97.5% of theory) of 3-(2-fluorobenzyloxy)-tetrahydrofurane of boiling point 140° C./14 mm Hg were obtained.
