Potassium Carbonate → 3-(4-Methyl-1-piperazine)propan-1-ol

Participants

Reaction Steps

3-Bromopropan-1-ol (20 ml, 20 mmol) was added dropwise to a solution of 1-methylpiperazine (29 ml, 26 mmol) in ethanol (200 ml). Potasium carbonate (83 gr, 60 mmol) was added and the mixture was refluxed for 20 hours. After cooling, the solid was filtered and the filtrate was evaporated. The residue was triturated with ether, filtrate and evaporated. The residue was distilled at about 60–70° C. under about 0.2 mm Hg to give 1-(3-hydroxypropyl)-4-methylpiperazine (17 g, 53%).
