With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.25637-16-5,4-Bromotetrahydropyran,as a common compound, the synthetic route is as follows.

In a glass flask having inner volume of 20 ml provided with stirrer, the thermometer, and the reflux condenser, 1.69 g (10.2mmol) of 4-bromotetrahydrofuran, potassium cyanide 1.0g (15.4mmol), and 10 ml of dimethyl sulfoxide were added and the mixture was reacted at 80 degrees C for 7 hours. After completion of the reaction, the reaction mixture was analyszed by gas chromatography (internal standard method), 0.10 g of 4-cyanotetrahydropyran was obtained (reaction yield: 9%).
