Reaction Steps

Hydrogen chloride in 1,4-dioxane (4.0M, 0.50 mL) was added to tert-butyl 8-(methylsulfonyl)-2,8-diazaspiro[4.5]decane-2-carboxylate (21.0 mg, 0.0000659 mol) at rt. The mixture was stirred at rt for 1 h and then the solvent was evaporated. and the residue was dried under high vacuum to afford the desired product. LCMS: m/z 255.5 (M+H)+
