64051-79-2,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.64051-79-2,3-Hydroxypiperidine Hydrochloride,as a common compound, the synthetic route is as follows.
10 Step 4: preparation of 3-Hydroxy-piperidine-1-carboxylic acid benzyl ester. Tosuspension of piperidin-3-ol hydrochloride (134 g, 0.974 mol) and triethylamine (276 mL, 1.98 mol) in dichloromethane (2 L) at 0 C was added a solution of benzyl chloroformate (140 mL, 0.981 mol) in dichloromethane (100 mL) drop wise over 2.5 h. The reaction was allowed to stir for an additional 30 mm at 0 C, then allowed to warm15 to ambient temperature over 16 h, after which it was quenched with 1 N hydrochloric acid (3 L) and allowed to stir for 30 mm. The organic layer was separated, dried over sodium sulfate, and concentrated in vacuo to afford the title compound (218 g, 95 %).1H-NMR (CDCI3) 67.29-7.41 (m, 5H), 5.14 (s, 2H), 3.59-3.85 (m, 3H), 3.13-3.27 (m, 2H), 2.18 (bs, 1H), 1.74-1.94 (m, 2H), 1.38-1.61 (m, 2H).
64051-79-2 3-Hydroxypiperidine Hydrochloride 2723962, apiperidines compound, is more and more widely used in various fields.
