With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.184950-35-4,(Tetrahydrofuran-3-yl)methanamine hydrochloride,as a common compound, the synthetic route is as follows.
2-Butyloxazole-5-carboxylic acid (0.10 g, 0.6 mmol), Tetrahydrofuran-3-ylmethylamine hydrochloride (0.12 g, 0.9 mmol), Triethylamine (0.09 g, 0.9 mmol) And 1-hydroxybenzotriazole (0.01 g, 0.1 mmol) Was added to chloroform (amylene added product) (1.2 mL). To the mixture, 1-Ethyl-3- (3-dimethylaminopropyl) carbodiimide hydrochloride (0.14 g, 0.7 mmol) was added at room temperature, After stirring overnight, Add water, And extracted three times with ethyl acetate. The organic layer was washed with saturated brine , Dried over anhydrous sodium sulfate, And concentrated under reduced pressure. The residue was subjected to silica gel column chromatography, Represented by the following equation N- (tetrahydrofuran-3-ylmethyl) -2-butyloxazole-5-carboxamide (Hereinafter referred to as present amide compound (59)) 0.13 g was obtained., 184950-35-4
As the paragraph descriping shows that 184950-35-4 is playing an increasingly important role.
