Microwave-assisted solution- and solid-phase synthesis of 2-amino-4-arylpyrimidine derivatives.


An efficient and rapid microwave-assisted solution-phase method for the synthesis of 2-amino-4-arylpyrimidine-5-carboxylic acid derivatives has been developed. The five-step linear protocol involves an initial Biginelli multicomponent reaction leading to dihydropyrimidine-2-thiones which are subsequently S-alkylated with methyl iodide. The resulting 2… (More)
