With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.65412-03-5,4-(2-Aminoethyl)tetrahydro-2H-pyran,as a common compound, the synthetic route is as follows.
5-Benzyloxymethyl isoxazole-3-carboxylic acid (0.35 g, 1.5 mmol), 2- (Tetrahydropyran-4-yl) ethylamine (0.23 g, 1.8 mmol) And 1-hydroxybenzotriazole (0.02 g, 0.15 mmol) Was added to chloroform (amylene added product) (7.5 mL). To the mixture, 1-Ethyl-3- (3-dimethylaminopropyl) carbodiimide hydrochloride (0.35 g, 1.8 mmol) was added at room temperature, After stirring overnight, And concentrated under reduced pressure. Dilute hydrochloric acid was added to the concentrate, Extracted twice with ethyl acetate. The organic layer was washed with saturated brine, After drying over anhydrous sodium sulfate, it was concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, Represented by the following equation N- [2- (tetrahydropyran-4-yl) ethyl] -5-benzyloxymethyl isoxazole-3-carboxamide (Hereinafter referred to as amide compound (18)) 0.43 g., 65412-03-5
65412-03-5 4-(2-Aminoethyl)tetrahydro-2H-pyran 2773198, aTetrahydropyrans compound, is more and more widely used in various fields.
