Hydrochloric Acid → HCID 22624502, compound

Participants

Reaction Steps

In 50 mL of anhydrous ether was dissolved 500 mg (0.9 mmol) of 4-(4-hydroxy-4-(2-(3-hydroxyhexyloxy)phenyl)piperidino)-N,N-dimethyl-2,2-diphenylbutaneamide (Compound No. 35). To the resulting solution was added 0.4 mL of a 4N solution of hydrochloric acid and dioxane under ice cooling and stirring. The white precipitate thus formed was collected by filtration, washed with ether and dried, whereby 460 mg (yield: 86.3%) of 4-(4-hydroxy-4-(2-(6-hydroxyhexyloxy)phenyl)piperidino)-N,N-dimethyl-2,2-diphenylbutaneamide hydrochloride (Compound No. 37) was obtained.
