実験手順

Ethyl 5-methyl-1H-1,2,4-triazole-3-carboxylate (3.0 g, 19.3 mmol) is placed in a sealed tube that is then charged with a solution of 7N NH3 in MeOH (40 mL). The reaction is stirred at 50° C. for 24 h. The solvent was then removed under reduced pressure and the crude material was used directly for the next step without further purification. MS (ES+) C4H6N4O requires: 126. found: 127 [M+H]+.
