4-乙基-1-哌嗪乙醇

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: 1-Ethylpiperazine (5.0 g, 43.8 mmol) was dissolved in 90 mL of acetonitrile, followed by the addition of powdered potassium carbonate (18.2 g, 131 mmol), and 2-bromoethanol (10.9 g, 87.6 mmol). This mixture was warmed to reflux for 16 hours, cooled to ambient temperature, and filtered. The filtrate was concentrated under reduced pressure and purified by column chromatography (10% MeOH/DCM/0.5% NH4OH) to give 5.4 g (78%) of 2-(4-ethylpiperazin-1-yl)ethanol as a light yellow oil. This mixture was warmed to reflux for 16 hours filtered The filtrate was concentrated under reduced pressure purified by column chromatography (10% MeOH/DCM/0.5% NH4OH)
