Participants

Reaction Steps

500 mg of 4-trifluoromethylnicotinic hydrazide were heated under reflux in 3.5 ml of triethyl orthoacetate for 2 hours. The reaction mixture was subsequently concentrated and the residue was carefully admixed with 2 ml of phosphorus oxychloride. The mixture was stirred at room temperature for 1 hour and then poured on ice and extracted with ethyl acetate. Chromatographic purification of the crude product obtained after drying and concentrating gave the desired compound as a yellowish oil.
