With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.125224-43-3,((3S,4R)-4-(4-Fluorophenyl)piperidin-3-yl)methanol,as a common compound, the synthetic route is as follows.
To a mixture of [(3S,4R)-4-(4-fluorophenyl)piperidine-3-yl]methanol (3.0 g, 14 mmol), sodium carbonate (6.1 g, 57 mmol), dichloromethane (40 mL) and water (40 mL) was added di-tert-butyl Bicarbonate (3.8 g, 17 mmol) under ice cooling, followed by stirring at the same temperature for 30 minutes. The reaction mixture was added to a mixed solution of dichloromethane and water, and the organic layer was separated. The organic layer was washed with brine and dried over anhydrous magnesium sulfate, and the solvent was distilled away under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate_heptane=1:1) to give the title compound (4.0 g, 90% yield). 1H-NMR Spectrum (CDCl3) delta (ppm): 1.49 (9H, s), 1.61-1.71 (1H, m), 1.75-1.85 (2H, m), 2.51-2.56 (1H, m), 2.71 (1H, dd, J=11.3, 13.2 Hz), 2.78 (1H, br s), 3.24-3.29 (1H, m), 3.42-3.46 (1H, m), 4.20 (1H, br s), 4.36 (1H, d, J=11.7 Hz), 6.97-7.03 (2H, m), 7.13-7.18 (2H, m).
125224-43-3, 125224-43-3 ((3S,4R)-4-(4-Fluorophenyl)piperidin-3-yl)methanol 9855829, apiperidines compound, is more and more widely used in various fields.
