Reaction Steps

Hydrogen chloride in methanol (1.25 mol/l, 15.5 ml) was added to tert-butyl 9-(azetidin-1-yl)-3-azaspiro[5.5]undecane-3-carboxylate (1 g, 3.24 mmol), and the mixture was refluxed for 45 min. The solvent was removed under vacuum and the residue was dissolved in a small amount of ethanol. A solid was then precipitated by addition of acetone, and finally diethyl ether was added and the resulting precipitate was filtered out with suction. Yield: 0.87 g (95%)
