Versuchsvorschrift

Sixty-two grams (0.30 mole) of 2-benzoylbenzaldehyde in 140 mL of THF was treated with 81.5 g (0.59 mole) of potassium carbonate and 64 g (0.32 mole) of benzylhydrazine dihydrochloride. The mixture was stirred 30 minutes at 0° and 40 mL of methylene dichloride was added. The mixture was stirred at room temperature for one day, filtered and stripped in vacuo to provide 131 g of 2-benzyl-1-phenyl phthalazinium chloride.
