Procedure

To a solution of 85% 4-[(S)-1-(2-methyl-propane-2-sulfinylamino)-propyl]-pyridine-2-carboxylic acid amide (5.5 g, 16.5 mmol) in methanol (50 mL) was added a 4 N solution of HCl in dioxane (4.33 mL, 17.32 mmol). After 2 hour, additional 4 N HCl in dioxane (0.5 mL) was added. The reaction was monitored by TLC (eluting with EtOAc). After 1.5 hours, the mixture was concentrated in vacuo to remove MeOH and EtOAc (400 mL) was added. The mixture was washed with saturated sodium carbonate solution (100 mL) and the aqueous layer was extracted with EtOAc (4×100 mL). The combined organic layers were washed with brine, dried over sodium sulfate, filtered and concentrated to afford 4-((S)-1-amino-propyl)-pyridine-2-carboxylic acid amide.
