Versuchsvorschrift

(E)-ethyl 3-((2-acetylhydrazono)methyl)-5-chloroisonicotinate (220 mg, 0.816 mmol) and aq. NaOH solution (3.26 mg, 0.082 mmol, 2 molar) in 5 mL of dioxane were stirred in a microwave at 165° C. for 60 min. Then the reaction mixture was basified by addition of aq. NaHCO3 and extracted with DCM. The organic phase was washed with brine, dried and concentrated. The crude title compound was purified by chromatography (eluent: DCM/methanol) to give 25 mg (16.88%) of the title compound as beige solid.
