Participants

Reaction Steps

15.4 g (0.11 mole) of benzoyl chloride are added at room temperature to a solution of 24.7 g (0.1 mole) of 1-phenyl-2-ethoxycarbonyl-3-amino-3-pyrazolin-5-one (compound 2),3 ml of nitrobenzene, and 26.7 g (0.2 mole) of anhydrous aluminium chloride in 100 ml of acetonitrile. The solution is refluxed for 3 h and then poured out into water. The precipitate is filtered off, rinsed with water, dried, and recrystallized from acetonitrile.
