The 1-position of 5-methyl-3-pyrazolidinone, which was synthesized by the cyclization of ethyl crotonate and hydrazine, was halogenated and then it was reacted with amines to give 1-alkylaminoacyl-5-methyl-3-pyrazolidinone derivatives. These compounds synthesized did not show any superior analgetic activities to aminopyrine.
