Versuchsvorschrift
Tetrahydro-3,5-bis-(phenylmethylene)-4H-thiopyran-4-one (5g) is refluxed with 2.1g of 3-dimethylaminopropylhydrazine in 50ml of methanol for 4 hours. The solvent is evaporated off and the residue is crystallized from 30ml of acetonitrile to yield 3.9g of the title compound, melting point 83°-85°C.
