Reaction Steps

To a solution of tert-butyl 3-propanoyl-3,7-diazaspiro[4.4]nonane-7-carboxylate (153 mg, 0.54 mmol) in DCM (0.5 mL) was added a solution of hydrogen chloride (1.4 mL of 4 M, 5.4 mmol) in dioxane. The reaction mixture was stirred at room temperature for 1 h. The solvents were removed under reduced pressure and the crude product was dried on the high vacuum for 1 h to yield 1-(3,7-diazaspiro[4.4]nonan-3-yl)propan-1-one as an off white gum. LC/MS m/z 183.3 [M+H]+.
