Reaction Steps

Hydrogen chloride (4M in dioxan, 1.0 mL, 4.00 mmol) was added to tert-butyl 1-(4-chlorophenyl)-3-sulfamoylpropylcarbamate (Intermediate 103) (38 mg, 0.11 mmol) in a mixture of DCM (5 mL) and methanol (2 mL) at 22° C. The resulting solution was stirred at 22° C. for 24 hours. The mixture was evaporated to dryness and the residue was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 30% (2M NH3 in MeOH) in DCM and pure fractions were evaporated to dryness to afford 3-amino-3-(4-chlorophenyl)propane-1-sulfonamide (20.00 mg, 73.8%) as a colourless gum.
