実験手順
Hydrogen chloride in methanol (1.25 mol/l, 6.3 ml) was added to tert-butyl-9-(pyridin-4-yl)-3,9-diazaspiro[5.5]undecane-3-carboxylate (0.52 g, 1.569 mmol), and the mixture was refluxed for 1 h. The solvent was removed in vacuo, and the residue was taken up in ethanol (3 ml) and cooled. Acetone (80 ml) was added and stirring was carried out for 30 min. in an ice bath. The precipitate was filtered out with suction, washed with diethyl ether and dried in vacuo. Yield: 0.4 g (83%) Alternatively, the deprotection can also be carried out under the action of TFA in DCM in order to obtain the amine (F-09) in the form of the free base.
