Abstract
With diethyl malonate and guanidine hydrochloride as the starting material,2,5-diamino-4,6-dihydroxypyrimidine was prepared by cyclization,nitration,reduction and acid reaction and its structure was confirmed through the melting point,MS,elemental analysis.At the same time,some measures were taken to investigate the processing technology in the fields of reaction condition and operation procedures,which effectively reduced the material cost,simplified operation and improved product quality.
