Synthesis Of New Pyrarolones As Potent Anti-Inflammatory Agents

l,2-Diphenyl-3,5-dichloropyrazolium perchlorate (1) obtained from the reaction of l,2-diphenyl-3,5-pyrazolidine-dione with phosphorous oxychloride in benzene, gave with different sod. salt of amino acids the following compounds:1. l,2-Diphenyl-3,5-bi3(carboxyiaopropylamino)pyrazoliuraperchlorate. 2 . 1,2-Diphenyl-3,5-bis(carboxypropylamino)pyrazoliumparchlorate 3-- l,2-Diphenyl-3,5-bis(carboxyphenylethylamino)pyrazoliumperchlorate.3-Chloro-l,2-diphenyl-3-pyrazolin-5-one was also obtained during this reaction as a by product.The carboxy alkylamino pyrazolium perchlorates (Ila-b)
