Wade, James J. published 《Synthesis of imidazo[1,5-c]pyrimidine derivatives》. The research results were published in《Journal of Heterocyclic Chemistry》 in 1986.Computed Properties of C5H5ClN2O2 The article conveys some information:
Two complementary procedures, each starting from 6-(aminomethyl)uracil (I), were used to prepare imidazopyrimidines II (R = H, Me, Pr, CHMe2, CMe3, Ph; R1 = morpholino, OMe, SPr, Me). I was prepared by ammoxidation of 6-(chloromethyl)uracil. In the first procedure, I was acylated and then cyclodehydrated by reaction with POCl3 to give a separable mixture of II and III (R1 = Cl). The relative product distribution is subject to some control by the choice of the acyl substituent on the starting uracil. II (R1 = Cl) were derivatized by reaction at the 5-position with various nucleophiles, although the 7-chloro substituent is unreactive. An alternative synthetic method proceeds from I in six steps, i.e. protection as the phthalimide, chlorination, nucleophilic substitution, deprotection, acylation, and cyclodehydration, to give II (R1 = SMe). These compounds were also derivatized by nucleophilic substitution at the 5-position.6-(Chloromethyl)pyrimidine-2,4(1H,3H)-dione (cas: 18592-13-7) were involved in the experimental procedure.
6-(Chloromethyl)pyrimidine-2,4(1H,3H)-dione (cas: 18592-13-7 Computed Properties of C5H5ClN2O2) was used in the synthesis of: 5-bromo-6-(chloromethyl)uracil, pteridine compounds, potential anticancer agents, substituted uracil pyridinium compounds, potential inhibitors of thymidine phosphorylase.
