Potassium Iodide → 2,2-Dimethyl-3-(piperidin-1-yl)propan-1-ol

참여 물질

반응 단계

A solution of 3.00 g (17.96 mmol) of 3-bromo-2,2-dimethyl-propan-1-ol, 17.78 ml (179.59 mmol) of piperidine, 2.48 g (17.96 mmol) of K2CO3 and 2.69 g (17.96 mmol) of potassium iodide in 20 ml of DMA were stirred at 70° C. for 20 h. After filtration and evaporation of the solvents, the crude product was dissolved in diluted aqueous HCl solution and washed with EtOAc (3×). The aqueous phase was basified with KHCO3 and some drops of 1N NaOH and extracted with EtOAc (3×). The organic phase was dried (Na2SO4) and evaporated to give 0.57 g (18%) of the title compound as yellow liquid. MS: 172.0 (MH+).
