Reaction Steps

{1-[3-Chloro-4-(3-phenyl-propionylamino)-benzenesulfonyl]-piperidin-4-yl}-carbamic acid tert-butyl ester (0.09 g, 0.1 mmol) was suspended in a 4M solution of HCl in Dioxane (5 ml). The resulting suspension was stirred at room temperature for 3 hours. After this time the solution was concentrated under vacuum to give the title compound (0.048 g, 99% yield) as a colourless oil which was taken on directly without further purification. Tr=1.71 min, m/z (ES+) (M+H)+ 422.
