With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.710972-40-0,tert-Butyl 4-((2-methoxyethyl)amino)piperidine-1-carboxylate,as a common compound, the synthetic route is as follows.
710972-40-0, Cvclopropylmethyl-{l-[2-(lH-indazol-4-yl)-4-morpholin-4-yl-thienor3,2- d1pyrimidin-6-ylmethyl1-piperidin-4-yl}-(2-methoxy-ethyl)-amine (108).Prepared via [l-(2-Chloro-4-mophiholin-4-yl-thieno[3,2-d]pyrimidin-6- ylmethyl)-piperidin-4-yl]-cyclopropylmethyl-(2-methoxy-ethyl)-amine, prepared from cyclopropylmethyl-(2-methoxy-ethyl)-piperidin-4-yl-amine. Amine preparation: l-BOC-4-piperidone (500mg) and 2-methoxyethylamine(218muL) were stirred in MeOH at room temperature. After 16 h, sodium borohydride was added (190mg) carefully. After a further 3 h, the reaction mixture was diluted with DCM, washed with water, dried (MgSO4) and the solvent removed in vacuo to yield 4-(2-methoxy-ethylamino)-piperidine-l-carboxylic acid tert-butyl ester (560mg).A mixture of 4-(2-methoxy-ethylamino)-piperidine-l-carboxylic acid tert- butyl ester (525mg), cyclopropylmethyl bromide (218muL) and potassium carbonate (340mg) was heated to reflux in MeCN for 16 h. After cooling the reaction mixture was diluted with chloroform, washed with brine, dried (MgSO4) and the solvent removed in vacuo to yield 4-[cyclopropylmethyl-(2-methoxy-ethyl)-amino]- piperidine-1-carboxylic acid tert-butyl ester (475mg). Removal of the BOC group with HCl yielded the desired compound, which was isolated as the hydrochloride salt.1H NMR (400MHz, CDCl3): -0.01-0.01 (2H, m), 0.40-0.48 (2H, m), 1.45-1.60 (3H, m), 1.62-1.70 (2H, m), 1.97-2.04 (2H, m), 2.33 (2H, d), 2.52-2.61 (IH, m), 2.67 (2H, t), 2.92-3.00 (2H, m), 3.25 (3H, s), 3.34 (2H, t), 3.71 (2H, s), 3.82 (4H, t), 4.00 (4H, t), 7.22 (IH, s), 7.49 (IH, t), 7.48 (IH, d), 8.28 (IH, d), 8.90 (IH, s), 10.00 (IH, br); MS (ESf) 562 (MH+).
The synthetic route of 710972-40-0 has been constantly updated, and we look forward to future research findings.
