Hydrazine hydrate (1:1) → HCID 54042176, compound

Participants

Reaction Steps

The mixture of 0.3 g of 9-cyano-2-fluoro-10,11-dihydrodibenzo[b,f]thiepin-11-one, 0.3 g of 100% hydrazine hydrate and 10 ml of ethanol was heated under reflux on waterbath for 5 hours. The reaction mixture was concentrated to 5 ml to separate crystals on cooling, which was collected by filtration. Recrystallization from ethanol afforded 0.3 g of 9-cyano-2-fluoro-10,11-dihydrodibenzo[b,f]thiepin-11-one hydrazone as pale yellow needles having a melting point of 220°-222° C.
