A convenient synthesis of 1-alkyl-1-phenylhydrazines from N-aminophthalimide

Nara, Shigeru,Sakamoto, Takeshi,Miyazawa, Etsuko,Kikugawa, Yasuo

, p. 87 - 98 (2007/10/03)

N-Alkylaminophthalimides were synthesized by condensation of N-aminophthalimide with aldehydes, and subsequent reduction of the intermediate with pyridine-borane in acetic acid. N-Phenylation and removal of the phthalimide group gave 1-alkyl-1-phenylhydrazines in high yield.
