Synthesis of benzoic acids and polybenzamides containing tertiary alkylamino functionality

Khan, Gul Shahzada,Dickson, Benjamin D.,Barker, David

, p. 1790 - 1801 (2012/03/11)

The high-yielding and easily scalable synthesis of a number of benzoic acids bearing a tertiary alkylamino functionality has been achieved. The flexible synthesis began from readily available aminobenzoic acids or terephthaloyl chloride and requires almost no chromatography. Coupling of the synthesised amino acids to a range of substituted anilines was achieved when utilizing a specific combination of DIC, HOBt and DMAP.
