Participants

Reaction Steps

106.8 g (0.44 mol) of 1-(2,4-dichlorophenyl)-2-(1,2,4-triazol-1-yl)-ethan-1-one were dissolved in 780 ml of ethanol, 48 g of hydroxylammonium hydrochloride were added and the mixture was heated under reflux for 5 hours. Thereafter, 1,000 ml of water were added, and the reaction mixture was filtered. 51 g (45% of theory) of 1-(2,4-dichlorophenyl)-1-oximino-2-(1,2,4-triazol-1-yl)-ethane of melting point 165°-170° C. were obtained. ##STR8##
