Participants

Reaction Steps

A mixture of 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, 30 parts of concentrate hydrochloric acid and 150 parts of acetic acid was stirred and refluxed for 24 hours. The reaction mixture was evaporated and the residue was dissolved in trichloromethane. The latter was dried, filtered and evaporated, yielding 7.2 parts of 2-[4-(1-cyano-1-phenylethyl)phenyl]-2,3,4,5-tetrahydro-3,5-dioxo-1,2,4-triazine-6-carboxylic acid (intermediate 86).
