Tetrahydro-2H-pyran-4-carbonylchloride Use and Manufacturing

Synthesis of tetrahydropyran-4-carboxylic acid chlorideIn a vessel made of a glass, having an inner volume of 50 ml and equipped with a stirring device, a thermometer and a reflux condenser were charged 6.85 g (52.6 mmol) of tetrahydropyran-4-carboxylic acid, 9.79 g (82.3 mmol) of thionyl chloride and 10 ml of toluene, and the mixture was reacted at 80° C. for 1.5 hours under stirring. After completion of the reaction, the reaction mixture was concentrated under reduced pressure to obtain 7.81 g (Isolation yield; 100percent) of tetrahydropyran-4-carboxylic acid chloride as pale brownish liquid.Physical properties of the tetrahydropyran-4-carboxylic acid chloride were as follows.Tetrahydropyran-4-carnboxylic acid (0.92g, 7.07 mmol) was dissolved in thionyl chloride (5.7 mL, 77.8 mmol) and refluxed for 2.5 h. After this time the mixture The starting tetrahydropyran-4-carboxylic acid (0.5 g, 4 mmol, 1.0 eq) was added to 10 mL of DCM and a catalytic amount ofDMF, and then 0.4 mL of thionyl chloride was added dropwise at 0 ° C. Dropping at room temperature for 1 h. The solvent and excess of thionyl chloride were vacuum dried to give 0.6 g of a colorless liquid which was used directly in the next step.
