Versuchsvorschrift

To a solution of compound 26-5 (70 mg) in AcOH—H2O (6 mL-2 mL), was added a solution of potassium cyanate (KOCN; 31 mg) in water (2 mL). The reaction mixture was stirred at 40-50° C. for 3 hours and at room temperature overnight to precipitate. The resulting precipitate was collected by filtration, rinsed with waster and dried in vacuo to obtain compound 27-1 (70 mg) as a colorless amorphous solid.
