Ammonia → HCID 20328011, compound

Participants

Reaction Steps

A solution consisting of 9.7 gm. (0.025 mole) ethyl 3,4,5-tribromopyrazole-1-acetate in 250 ml. ethanol was saturated with gaseous ammonia and held at about 25° C. for 3 days. After removing most of the ethanol by evaporation under reduced pressure, the solids that formed were collected on a filter and recrystallized from a mixture of ethanol and water. There was thus obtained 5.8 gm. of 3,4,5-tribromopyrazole-1-acetamide having a melting point at 234° to 236° C.
