Sodium Chloride → 1-(3-Methyl-3-phenylbutyl)piperazine

Participants

Reaction Steps

A solution of ethyl 4-(3-methyl-3-phenylbutyl)piperazine-1-carboxylate (1.17 g) in conc. hydrochloric acid (15 ml) was heated in a sealed tube for 12 hours at 120° C. The solution was concentrated and to the resultant residue was added 10% sodium hydroxide to make basic. The mixture thus obtained was saturated with sodium chloride and extracted with ethyl acetate. The ethyl acetate layer was washed with a saturated aqueous solution of sodium chloride, dried over anhydrous sodium sulfate and concentrated to give 0.85 g of 1-(3-methyl-3-phenylbutyl)piperazine.
