, (2008/06/13)
A process for synthesizing an N,N-disubstituted hydrazone comprises carrying out nitrozation by adding an aqueous solution of sodium nitrite to a solution having one part by weight of an N,N-disubstituted amine dissolved in 3 to 30 parts by weight of an organic acid, then reducing the nitrozated product to an N,N-disubstituted hydrazine by adding a reducing agent to the mixture containing the nitrozated product, and thereafter adding to the mixture containing the N,N-disubstituted hydrazine a carbonyl compound of the formula: STR1 wherein A represents an aromatic hydrocarbon group or an aromatic heterocyclic group which may have a substituent, B represents a hydrogen atom, an alkyl group, an aryl group or an aromatic heterocyclic group, which may have a substituent, thereby performing condensation of the N,N-disubstituted hydrazine with the carbonyl compound.
