A new method for the protection of primary amines or amino alcohols as phthalimides is described. The phthaloyl group is selectively introduced under mild, anhydrous conditions by reacting the amine with 2- (ethoxycarbonyl)benzoic acid activated by PyBOP, followed by the thermally induced cyclization of the resulting phthalamic ester. These reaction conditions are applicable to a variety of primary amines and good yields are obtained in all cases.

The reaction of primary diamines with phthaloyl chloride leads to the formation of N,N'-disubstituted isophthalimides and not the bicyclic imides of phthalic acid as considered earlier.
