To protect the β-amine group of phenylhydrazine with an aldehyde or ketone, the phenyl group is chlorinated,
Next, reduction was performed using zinc or the like. However, this method has the disadvantage that since the zinc used in the reduction usually contains cadmium as an impurity, disposal of the reaction residue poses a pollution problem and the processing cost is high. Furthermore, when aldehydes and ketones used as protective groups for the nitrogen atom at the β-position of phenylhydrazine are removed by reduction, they are released as compounds in which the bond with the nitrogen atom at the β-position becomes a methyl group or a medilene group. It is difficult to reuse it as a protecting group, and it has the disadvantage of increasing costs.
