Synthesis of 4-substituted pyrido[2,3-d]pyrimidin-4(1H)-one as analgesic and anti-inflammatory agents

4-Substituted-pyrido[2,3-d]pyrimidin-4(1H)-ones 4a-c were synthesized by oxidation of 4-substituted-dihydropyrido[2,3-d]pyrimidin-4(1H)-ones 3a-c which were in turn prepared from arylidenemalononitriles 1a-c and 6-aminothiouracil 2. The reactivity of comp
