Procedure
The solution of equivalent amounts of 2-chloro-4-fluorobenzoyl isocyanate in acetonitrile was added dropwise to the solution of 71 mg of 2-(4-amino-3-methylphenyl)-5-methyl-1,2-dihydropyrazol-3-one in 6 ml of acetonitrile and the mixture was stirred at room temperature overnight. The solid formed was filtered off with suction and dried under reduced pressure.
