Participants

Reaction Steps

In a reaction flask 5 mg of palladium on charcoal were added to 50 mg of 4-isopropylbenzenesulfonic acid 6-(4-allyl-piperazin-1-yl)-pyridin-3-yl ester from example 59(0.12 mmol) in dry ethyl acetate (5 ml). The atmosphere was then charged with hydrogen gas and the reaction mixture was stirred at room temperature for 1 hour. Thereby, 4-isopropyl-benzenesulfonic acid 6-(4-propyl-piperazin-1-yl)-pyridin-3-yl ester were obtained in 58% yield. The compound was converted into its hydrochloride salt by addition of HCl in ether.
