Reaction Steps
Scheme 2 shows the synthesis of 4-(methylsulfonyl)piperazin-1-ium chloride 8 starting by N-sulfonylation of 1-(tert-butoxycarbonyl)piperazine 6 (BOC-piperazine) with methanesulfonyl chloride to give tert-butyl 4-(methylsulfonyl)piperazine-1-carboxylate 7 which was treated with aqueous hydrogen chloride solution in 1,4-dioxane to give 8.
