Reaction Steps

303 mg of 3-benzoyl isoquinoline and 9.75 g of hydrazine hydrate were dissolved in 10 mL of ethylene glycol at room temperature, followed by stirring at 150° C. After 10 minutes, to the reaction liquid was added 3.65 g of pulverized potassium hydroxide, followed by warming to 180° C. and continuously reacting for additional 2 hours. After completion of the reaction, the reaction liquid was left to be cooled, and water was added thereto, followed by extraction with diethyl ether. The organic layer was washed with saturated brine, dried over anhydrous sodium sulfate, and then concentrated under reduced pressure. The residue obtained was purified using silica gel chromatography (diethyl ether:n-hexane=1:1) to obtain 280 mg (yield 95%) of a title compound as a light yellow solid.
