Versuchsvorschrift

Compound 39 (470 mg, 1 mmol) was dissolved in MeOH (15 mL) and THF (15 mL). Raney Nickel (50% slurry in water) (2 mL) was added to the reaction mixture followed by anhydrous hydrazine (1 mL). The reaction mixture was stirred at room temperature for 30 minutes until the bubbling was stopped. The solid was filtered off through Celite under reduced pressure and washed with MeOH. The solvent was removed under reduced pressure. Liquid-liquid extraction was performed using CHCl3 (15 mL) and H2O (8 mL×2). The organic layer was dried over MgSO4, filtered and concentrated to give the compound 40 (263.8 mg, 59.9% crude yield) LC-MS (ESI): m/e=441.1 [M+1]+
