Reaction Steps
2.5 g of 6-chloropiperonyl alcohol are dissolved in 80 ml of ethyl ether. The solution is cooled to 0° C. and then 1.9 ml of PBr3 are added. The mixture is stirred at ambient temperature for 18 hours. It is poured onto ice and then extraction is carried out with AcOEt. The organic phase is washed with a saturated NaCl solution. 3.3 g of powder are obtained.
