Dimethylformamide → 1-t-Butoxycarbonyl-4-[3-(2-furyl)propyl]-piperazine

Participants

Reaction Steps

To a mixture of 1.16 g of 1-tert-butoxycarbonylpiperazine, 1.47 g of 2-(3-iodopropyl)furan and 20 ml of N,N-dimethylformamide was added 0.86 g of anhydrous potassium carbonate, and the mixture was stirred overnight at room temperature. To the reaction solution was added 300 ml of ethyl acetate, the solution was washed successively with water and saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and concentrated under reduced pressure. The residue was subjected to column chromatography and eluted with ethyl acetate to give 1.5 g of oily 1-tert-butoxycarbonyl-4-[3-(2-furyl)propyl]piperazine.
