Treatment of the readily available 6-amino-5-nitrosopyrimidines with a slight excess of iodobenzene diacetate or N-iodosuccinimide in anhydrous DMF containing three equivalents of lithium hydride at ambient temperature resulted in the smooth and versatile formation of the corresponding furazano[3,4-d]pyrimidines, which are useful intermediates for the preparation of biologically interesting fused pyrimidines.
