Versuchsvorschrift
Tert-butyl 1-(2-(3,5-dichlorophenylamino)acetyl)-4-methylpiperidin-3-ylcarbamate (150 mg, 0.36 mmol) was treated with dioxane.HCl (5 mL) at rt for 2 h. The solvent was concentrated in vacuo, the resulting residue was dissolved in water (10 mL) and treated with solid NaHCO3. The aqueous solution was extracted with EtOAc (3×25 mL) and the combined organic layers were dried over Na2SO4, concentrated in vacuo to yield the titled intermediate (100 mg, 87%), which was used next without further purification. LC-MS: m/z [M+1]=316.
