Reaction Steps

A mixture of ethyl 7-hydroxy-1,2,4-triazolo[1,5-a]-pyrimidine-6-carboxylate (5.6g. 25mM) and 2N hydrochloric acid (40ml) was heated under reflux for 5 hours. The reaction mixture was cooled and filtered to give the required product in 67.3% weight yield (3.30g). m.p. 296° C (decomposition). νmax (KBr disc) 1725 (acid C=O)cm-1 ; λmax (NaHCO3 solution) 293nm (εm 14,900); (Found: C, 40.27; H, 2.35; N, 30.49%. C6H4N4O3 requires C, 40.01; H, 2.24; N, 31.10%).
