Reaction Steps

A portion of the t-butyl 4-(1-benzenesulfonyl-1H-indol-4-yl)piperazine-1-carboxylate (0.85 g) is stirred in a mixture of 4N HCl and dioxane at room temperature for 2 hrs and filtered. The filtercake is dried to give the title product as a while solid, 0.64 g (99% yield) mp 60° C. identified by mass spectral and NMR analyses.
