Synthesis and halogenation of propargyl pyrazolo-[3,4-d]pyrimidine thioether

The reaction of 4-imino-1-methyl-5-phenyl-6-propargylthio-1,5-dihydro-4H- pyrazolo[3,4-d]pyrimidine with halogens leads to the formation of (Z)-8-halomethylene-4-imino-1-methyl-5-phenyl-4,5,7,8-tetrahydro-1H-pyrazolo[4, 3-e][1,3]thiazolo[3,2-a]pyrimidinium trihalide.
