Ethanol → Ethyl chloro[2-(2,4,6-trichlorophenyl)hydrazinylidene]acetate

Participants

Reaction Steps

A solution consisting of 17.0 g. )0.05 mole) chloroglyoxyloyl chloride (2,4,6-trichlorophenyl)hydrazone and 200 ml. ethanol was heated at the reflux temperature for 30 min. This reaction solution was then concentrated to a volume of about 50 ml. and cooled. The solids that separated were recovered on a filter, and the solids on the filter were recrystallized two times from technical hexane to give ethyl chloroglyoxylate 2-(2,4,6-trichlorophenyl)-hydrazone having a melting range at 65° to 73° C.
