Reaction Steps

Add 4N hydrogen chloride in dioxane (0.5 mL) to a solution of 5-tert-butoxycarbonylaminomethyl-2-(3-methyl-butyryl)-pyridine (60 mg, 0.2 mmol) in anhydrous dichloromethane (2 mL) and stir the solution overnight. Concentrate in vacuo and partition the residue between saturated aqueous NaHCO3 and dichloromethane. Extract the aqueous phase with dichloromethane (2×15 mL) and EtOAc (2×15 mL). Dry the combined organic extracts over Na2SO4, filter and concentrate in vacuo to obtain the title compound (37 mg, 95%) that was used without any further purification.
