Participants

Reaction Conditions

Reaction Steps

2 g of silver oxide and then 2 ml of propyl iodide were added to a solution of 4 g of 3-(3',4'-dimethoxyphenyl)-piperidine in 20 ml of chloroform and the mixture was stirred for 8 hours at 20° C under an inert atmosphere. Another 1 g of silver oxide and 1 ml of propyl iodide were added and the mixture was stirred for 15 hours. The mixture was filtered and the filtrate was evaporated to dryness. The residue was chromatographed over silica gel and eluted with a 6-3-1 cyclohexane-chloroform-triethylamine mixture to obtain 3.2 g of N-propyl-3-(3',4'-dimethoxyphenyl)-piperidine.
