Synthesis & Pharmacological Evaluation of Ethyl 3-Substituted-phenyl-2-methylmercapto/ phenyl/ methyl-4(3H)-pyrimidone-5-carboxylates

A number of ethyl 3-substituted-phenyl-2-methylmercapto/ phenyl/ methyl-4(3H)-pyrimidone-5-carboxylates (V) have been prepared by the reaction of amidines (III) with diethyl ethoxymethylenemalonate.In order to confirm the structure (V), ethyl 3-(2'-methylphenyl)-2-methylmercapto-4(3H)pyrimidone-5-carboxylate (103) has been transformed into the earlier synthesised 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone (115) by decarboxylation of 3-(2'-methylphenyl)-2-methylmercapto-4(3H)-pyrimidone-5-carboxylic acid (114), obtained by the alkaline hydrolysis of 103.Someof these compounds have shown antiinflammatory, diuretic and antipassive cutaneous anaphylaxis activities.
