Reaction Steps

3-Phenyl propionyl chloride (0.29 g, 1.76 mmol) was added in one portion to a solution of [1-(4-amino-3-chloro-benzenesulfonyl)-piperidin-4-yl]-carbamic acid tert-butyl ester (0.57 g, 1.4 mmol) in Pyridine (5 ml) and the mixture was heated to 60° C. The mixture was stirred at this temperature under a nitrogen atmosphere for 12 hours. After this time the mixture was diluted with DCM (100 ml) and washed sequentially with HCl (1M solution, 50 ml), NaOH (1M solution, 50 ml) and brine (50 ml). The organic layer was separated, dried (MgSO4), filtered and concentrated. The resulting residue was purified by flash column chromatography (elution: 98% DCM, 2% Methanol) to give the title compound (0.09 g, 8% yield) as a white powder. Tr=2.41 min, m/z (ES+) (M+Na)+ 545.
