Synthesis of 2,8-disubstituted 1,2,4-triazolo[5,1-i]purines

This paper describes the preparation of 2-aryl-8-fluorobenzyl-1,2,4-triazolo[5,1-i]purines 2, starting from 2-aryl-7,8-diamino-1,2,4-triazolo[1,5-c]pyrimidines 9. Our synthetic procedure represents the first example of a feasible approach for the synthesi
