Dimethylamine → HCID 53799959, compound

Participants

Reaction Steps

The original compound (II) can be prepared by ammonolysis, aminolysis, or by ester exchange from, for example, 1-[2-(2-chlorobenzoyl)-4-chlorophenyl]-2-(1-amino-1-ethoxycarbonylmethylene)hydrazine (IIa) [Japanese Patent Kokai 101396/1974]. For example, IIa is reacted with dimethylamine to give 1-[2-(2-chlorobenzoyl)-4-chlorophenyl]-2-(1-amino-1-dimethylcarbamoylmethylene)hydrazine (IIb): ##STR20## Still, another original compound (II), in particular 1-(2-benzoyl-4-chlorophenyl)-2-(1-amino-1-dimethylcarbamoyllmethylene)hydrazine (IIc) is prepared as follows: ##STR21## Thus, the compound (IIc) is prepared by reacting a diazonium salt of 2-amino-5-chlorobenzophenone with the compound (XIV), brominating the resulting compound (XI) and treating with aqueous ammonia; or reacting a diazonium salt of 2-amino-5-chlorobenzophenone with the compound (XV) and treating the resulting product (XIII) with aqueous ammonia.
