Abstrakt:	The corresponding hydrazones, which on heating are cyclized to give 1-phenyl-3-methyl-4-alkyl-(benzyl)-4-(2-oxopyrrolidinomethyl)- and 1-phenyl-3-methyl-4-alkyl(benzyl)-4-(N-methylcaprolactyl)pyrazolones, are formed in the reaction of alkyl(benzyl) (2-oxopyrrolidinomethyl)- and alkyl-(benzyl) (N-methylcaprolactyl)acetoacetic esters with phenylhydrazine.
