Abstract The aminopyrimidines(2) were obtained via the substitution reaction of 4,6-dichloro-2-(propylthio)pyrimidin-5-amine with primary amines. Diazotization and coupling reaction of 2 provided thiazoles(3). Twenty-six novel triazolo［4,5-d］pyrimidin compounds(6a~6z) were synthesized by the nucleophilic subsititution reaction of 3 with substituted amines and hydrolysis orderly. The structures were characterized by 1H NMR and ESI-MS. The anti-platelet aggregation activities were evaluated by platelet aggregation inhibition tests in rats. The results showed that 6a~6z exhibited certain anti-platelet aggregation activities. The inhibition rates of 6d, 6i and 6l were 61.9%, 69.3% and 71.2%, respectively.
