Versuchsvorschrift
To a solution of ethyl 3-oxo-3-(1-phenyl-1H-pyrazol-5-yl)propanoate (300 mg) in DMF (10.0 mL) was added benzenecarboximidamide (139 mg) at room temperature. The reaction mixture was heated using a microwave reactor at 140° C. for 30 min. The reaction mixture was extracted with dichloromethane. The extract was washed with saturated brine, dried over anhydrous sodium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (dichloromethane/methanol) to give the title compound (100 mg).
