Reaction Conditions

Reaction Steps

TFA (4 mL) was added to tert-butyl 1-(4-chlorophenyl)-3-(methylsulfonamido)propylcarbamate (Intermediate 115) (275 mg, 0.76 mmol) and stirred at 20° C. for 2 hours. The reaction was vacuumed to dryness. The crude product was purified by ion exchange chromatography, using an SCX column. The desired product was eluted from the column using 7M NH3/MeOH and pure fractions were evaporated to dryness to afford N-(3-amino-3-(4-chlorophenyl)propyl)methanesulfonamide (113 mg, 56.7%) as a colourless gum.
