With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1155-56-2,1-Benzyl-N-phenylpiperidin-4-amine,as a common compound, the synthetic route is as follows.
Reference Example 3 To a mixture of N-(1-benzyl-4-piperidinyl)aniline (1.8 g), diisopropyl ether (20 ml) and triethylamine (0.87 g) is added dropwise a solution of beta-n-butoxyacrylic acid chloride (1.4 g) in diisopropyl ether (5 ml) with stirring and heating at 70 C. After completion of dropwise addition, the mixture is further stirred with heating at the same temperature for 0.5 hour. After cooling, water is added to the reaction mixture and the mixture is subjected to extraction with ethyl acetate. The extract is washed with water and dried over magnesium sulfate. The solvent is distilled off under reduced pressure and the resulting residue is purified by silica gel column chromatography to give N-(beta-n-butoxyacryloyl)-N-(1-benzyl-4-piperidinyl)-aniline (2.6 g). NMR (CDCl3) delta: 0.86 (3H, t, J=7.1 Hz), 1.2-1.4 (1H, m), 1.4-1.6 (2H, m), 1.6-1.9 (2H, m), 2.1-2.3 (1H, m), 2.4-2.6 (3H, m), 2.7-2.9 (1H, m), 3.4-3.7 (4H, m), 4.86 (1H, d, J=12 Hz), 5.1-5.3 (1H, m), 7.1-7.5 (10H, m), 7.47 (1H, d, J=12 Hz)
1155-56-2, The synthetic route of 1155-56-2 has been constantly updated, and we look forward to future research findings.
