Nitrogen → 2-(3-Chloropropyl)tetrahydrofuran

참여 물질

반응 단계

To 3-(tetrahydrofuran-2-yl)propan-1-ol (3.90 g, 30.0 mmol) was added dichlorosulfoxide (15 mL) dropwise under N2 and the mixture was refluxed for 3.5 h. It was then cooled to rt and concentrated in vacuo. To the residue was added water (30 mL) and the resulting mixture was extracted with DCM (30 mL×4). The combined organic layers were washed with brine (40 mL×2), dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound as yellow liquid, which was used for next step without further purification.
