Benzene, (2-chloroethoxy)- → Phenoxyethyl-norfentanyl

Participants

Reaction Steps

By condensing 14.7 g 4-(N'-phenyl-N'-propionylamino)-piperidine and 19.9 g phenoxyethyl chloride, they are obtained after 24 hours reflux 22 g of the title product which after recrystallization from hot cyclohexane gives a first crop weighing 13.5 g. The pure compound melts at 100°-102°. It is soluble in hydrochloric acid. The solution after distillation leads to the recovery of the hydrochloride. The hydrochloride is soluble in water.
