Synthesis and pharmacological profile of novel N-substituted N-[5H-[1]benzopyrano[4,3-d]pyrimidin-2-YL]-N-methylglycinamides

The title compounds were synthesized by cyclizing 3-dimethylaminomethylene-4-chromanone with creatine to give the acid 2 that was successively converted into the corresponding amides 3a-f via diphenylphosphorylazide and the relevant amines. The free acid 2 and some of 3a-f showed antiinflammatory, hypotensive and antiarrhythmic properties.
