Reaction Steps

In 5 mL of ethanol is dissolved 0.06 g of ethyl 5-oxo-4,5-dihydro-1,2,4-triazine-6-carboxylate. At 10° C., the solution is saturated with ammonia by introducing gaseous ammonia thereinto for 20 minutes. The solution is allowed to stand at ambient temperature for 15 hours, and the resulting crystals are collected by filtration. The crystals thus obtained are washed successively with two 2 mL portions of ethanol and then two 1 mL portion of methanol to obtain 0.03 g of 5-oxo-4,5-dihydro-1,2,4-triazine-6-carboxamide.
