The invention relates to a novel method for producing 4- [(2',5'-diamino- 6'-halopyrimidine- 4'-yl)amino]- cyclopent- 2-enylmethanols of general formula (I), wherein X represents a halogen atom. According to the inventive method, a 2,5-diamino-4,6-halopyrimidine of general formula (II), wherein X has the aforementioned meaning, is reacted with a 4- aminocyclopent-2- enylmethanol of formula (III) or with a salt thereof in the presence of a base in a polar protic solvent. |
