An Efficient Scalable Synthesis of 2,3-Epoxypropyl Phenylhydrazones
Abstract
A series of mono and di-N-2,3-epoxypropyl N-phenylhydrazones have beenprepared on a large scale by reaction of the corresponding N-phenylhydrazones of9-ethyl-3-carbazolecarbaldehyde, 9-ethyl-3,6-carbazoledicarbaldehyde, 4-dimethyl-amino-, 4-diethylamino-, 4-benzylethylamino-, 4-(diphenylamino)-, 4-(4,4-4'-dimethyl-diphenylamino)-, 4-(4-formyldiphenylamino)- and 4-(4-formyl-4'-methyldiphenyl-amino)benzaldehyde with epichlorohydrin in the presence of KOH and anhydrousNa2SO4.
