Hydrazine hydrate (1:1) → HCID 117839459, compound

Participants

Reaction Steps

To an ethanol solution (1.0 mL) of (S)-2-[4-(4-fluorophenyl)-1,2,3,6-tetrahydropyridin-3-yl]isoindoline-1,3-dione (170 mg, 0.402 mmol) synthesized in Reference Synthesis Example 210, hydrazine monohydrate (150 mg, 3.00 mmol) was added and the resultant mixture was stirred under reflux by heating for 2 hours. After completion of the reaction, the reaction solution was filtered and the filtrate was concentrated under reduced pressure. Ethyl acetate was added to the obtained residue and the resultant mixture was filtered again, followed by concentrating the resultant filtrate under reduced pressure to obtain the title compound (46.0 mg, yield 59%).
