Dimethylcarbamoyl Chloride → HCID 20309760, compound

Participants

Reaction Steps

To 2.13 g. (0.01 mole) of 3,5-di(4-pyridyl)-1,2,4-triazole in 200 ml. of tetrahydrofuran is added 57% sodium hydride in mineral oil (0.42 g., 0.01 moles). The reaction mixture is heated at reflux for 1 hour, cooled and a solution of dimethylcarbamoyl chloride (1 g., 0.01 mole) in 10 ml. of tetrahydrofuran is added dropwise. The reaction mixture is heated at reflux for 4 hours, cooled, filtered and concentrated to an oil which solidifies. After recrystallization from benzene 1.2 g. of 1-dimethylcarbamoyl-3,5-di(4-pyridyl)-1,2,4-triazole melting at 140°-141.5° C. is obtained.
