Abstract
Substituted 3-anilinopropanamides were converted to N-benzyl derivatives via uncatalyzed amine exchange reaction with benzylamine in up to 41% yield. Unprotected aniline nitrogen had been observed to inhibit facile cyclization. An attempt was therefore made to protect the N by acetylation prior to cyclization. During this process, facile ring closure occurred in the methoxy series to give 4-hydroxy-4-N-benzylamino-1,2,3,4-tetrahydroquinolines in up to 69% yield.
