BOC-2-PIPERIDYLMETHANOL - Reference Information
| properties | 2-(hydroxymethyl) piperidine -1-tert-butyl formate has a melting point of 74-78°C, a boiling point of 308.0±15.0°C(Predicted), a density of 1.059±0.06g/cm3(Predicted), and an acidity coefficient (pKa) of 15.08±0.10(Predicted). |
| use | 2-(hydroxymethyl) piperidine -1-tert-butyl formate and its derivatives have good biological activity, and can not only be used to synthesize GABA intake inhibitors and anti-tumor drugs, it can also synthesize growth hormone secretagogue, anti-inflammatory and analgesic drugs, cardiovascular drugs, intelligence-promoting drugs, anti-influenza virus drugs and bone disease drugs. |
| synthesis method | triethylamine (23.34 mL,156.42 mmol) is added dropwise to the solution of 2-piperidine methanol (5.00g,43.45 mmol) stored in dichloromethane (150 mL), and the solution is stirred for 1 hour after complete addition. The solution of di-tert-butyl dicarbonate (Boc2O,11.38g,52.14 mmol) stored in dichloromethane (20 mL) was then added dropwise to the solution and stirred for extra hours after complete addition. Pour the reactant into 50 mL of water. The organic phase was extracted with water and the aqueous phase was extracted with dichloromethane (220 mL). The combined organic phase was washed with brine, dried by MgSO4 and filtered, and the solvent was removed in vacuum. The crude product was purified by column chromatography using silica gel and hexane/EtOAc(1:1) to obtain white solid ethanol 4(7.865g,84%). Several peaks in 1H NMR appear broadening due to the presence of a rotating body associated with carbamate. the yield of 2-(hydroxymethyl) piperidine -1-tert-butyl formate was 7.865g,84%.
