Participants

Reaction Steps

A mixture of 7.8 parts of ethyl[2-cyano-2-[[4-(1-cyano-1-phenylethyl)phenyl]hydrazono]acetyl]carbamate, 1.98 parts of anhydrous potassium acetate and 120 parts of acetic acid was stirred and refluxed for 3 hours. The reaction mixture was concentrated to a volume of 30 parts. Water was added till the product was precipitated. It was sucked off, washed with water and dissolved in trichloromethane. The remaining water was separated and the organic phase was dried, filtered and evaporated, yielding 6.86 parts of 2-[4-(1-cyano-1-phenylethyl)phenyl]-2,3,4,5-tetrahydro-3,5-dioxo-1,2,4-triazine-6-carbonitrile as a residue (intermediate 65).
