Versuchsvorschrift

Ethyl cis(±)-2-(3-azido-4-{[(4-chloro-5-ethyl-1H-imidazol-2-yl)carbonyl]amino}piperidin-1-yl)-1,3-benzothiazole-7-carboxylate obtained in Example (81d) (84 mg, 0.17 mmol) was dissolved in THF (3 mL). Triphenylphosphine (63 mg, 0.24 mmol) and distilled water (0.2 mL) were added, and the mixture was heated under reflux for 15 hours. The reaction solution was concentrated under reduced pressure and the precipitated solid was collected by filtration, to obtain 59.6 mg of the title compound as a white solid (75%).
