Abstract
Tertiary aminoaryl compounds, such as N,N'dialkylaminoaryl compounds, are prepared using successive reductive steps without isolation therebetween, at high temperature and pressure. A nitroaryl compound is reduced using a ketone as both solvent and reactant in a reductive environment, and the resulting intermediate is further reacted with an aldehyde in the same reaction mixture without isolation to provide the second substituent on the amino group.
