With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.936130-82-4,Methyl 4-(piperidin-4-yl)benzoate hydrochloride,as a common compound, the synthetic route is as follows.
936130-82-4, To a stirred solution of methyl 4- (quinidin-4-yl) benzoate (5.0 g, 22.8 mmol) andPotassium carbonate (25.0 g, 182.2 mmol) in tetrahydrofuran (50 ml) / water (50 ml) was added portionwiseDi-n-butyl dicarbonate(10.0 g, 45.8 mmol) and keep the temperature below 10 C. After adding,The reaction mixture was stirred at room temperature for an additional 0.5 hour and then diluted with water (50 ml)And extracted with ethyl acetate (50 ml x 2). The combined organic layers were washed with brine,Dried over anhydrous sodium sulfate and concentrated in vacuo. The residue was purified by silica gel column chromatography (eluent: petroleum ether / ethyl acetate = 6/1 to 1/1) to give4- (4- (methoxycarbonyl) phenyl) piperidine-1-carboxylic acidThe third butyl ester(1.9 g, yield: 26.4%) as a white solid.
936130-82-4 Methyl 4-(piperidin-4-yl)benzoate hydrochloride 42614593, apiperidines compound, is more and more widely used in various fields.
