Participants

Reaction Steps

An ethanol solution (100 ml) of 4-fluoro-4'-methylmercaptomethylbenzophenone (7.8 g), ethyl carbazate (9.4 g) and acetic acid (9 ml) was heated for 20 hours with refluxing. The solvent was distilled off under reduced pressure, and then the obtained oily substance was diluted with dichloromethane, and washed successively with an aqueous 5% sodium hydroxide solution, water and an aqueous saturated sodium chloride solution, followed by drying over anhydrous magnesium sulfate. The solvent was then distilled off to obtain 4-fluoro-4'-methylmercaptomethylbenzophenone ethoxycarbonylhydrazone (6.4 g) as an isomer mixture.
