Reaction Steps

Add 4N hydrogen chloride in dioxane (5.5 mL, 22 mmol) to a solution of N-(tert-butoxycarbonyl)-4-(3,3-dimethyl-butyryl)-2-fluoro-benzylamine (600 mg, 1.85 mmol) in dichloromethane (22 mL) and stir for 6.5 h. Concentrate in vacuo and wash the solid obtained with diethyl ether. Suspend the solid into saturated aqueous NaHCO3 and stir for 30 min. Extract the aqueous phase twice with EtOAc. Dry the combined organic extracts over Na2SO4, filter and concentrate in vacuo to obtain the title compound as an oil (420 mg, 99%).
