Dimethylamine → HCID 53799959, compound

Participants

Reaction Steps

To a suspension of 1-[2-(2-chlorobenzoyl)-4-chlorophenyl]-2-(1-amino-1-ethoxycarbonylmethylene)hydrazine (24.9 g) in methanol (300 ml), excess of gaseous dimethylamine is introduced at room temperature, and the reaction mixture is allowed to stand overnight. After evaporating the solvent under reduced pressure, the residue is recrystallized from ethanol to give 1-[2-(2-chlorobenzoyl)-4-chlorophenyl]-2-(1-amino-1-dimethylcarbamoylmethylene)hydrazine (21.3 g) as reddish orange crystals melting at 150 to 151° C. The yield is 85.5%.
