Participants

Reaction Steps

100 mg (0.24 mmol) of N-[6-(4-allyl-3-methylpiperazin-1-yl)pyridin-3-yl]-4-isopropylbenzenesulfonamide hydrochloride from Example 13.4 were dissolved in 10 ml of ethyl acetate, after which 10 mg of palladium on active charcoal (10%) were added and the mixture was stirred overnight at room temperature under a hydrogen atmosphere. After that, the catalyst was filtered off and the filtrate was evaporated down to dryness. After 1 ml of dichloromethane had been added to the resulting residue, diethyl ether was slowly added dropwise until the solution became cloudy. The reaction mixture was stirred for 30 minutes and the precipitate which had formed was filtered off with suction. The filtrate was evaporated down to dryness, after which the residue was dissolved in a 1:1 mixture of dichloromethane and diethyl ether and converted into the hydrochloride by adding ethereal hydrochloric acid. 71 mg (63% of theory) of the title compound were obtained.
