Abstract
Abstract 4-(3-Iodopropargyloxy) pyrimidine derivatives of the general formula <IMAGE> wherein R1 is selected from among a halogen atom, an amino group, a C1-C4 alkylamino or a C1-C4 alkylthio group, and R2 is selected from among a hydrogen atom, a halogen atom, a C1-C4 alkyl group or a C1-C4 alkoxy group, are disclosed. The described compounds are prepared by reacting a 4-halopyrimidine with propargyl alcohol and iodinating the resultant product in the 3 position of the propargyl chain.
