ABSTRACT:
For the preparation of pure, anhydrous cyclic imido esters, nitriles are reacted with amino alcohols with splitting off of ammonia at temperatures of 90.degree.-230.degree. C. under a pressure of 1.1-10 bar. The catalysts employed are metallic compounds. The process results in substantially shorter reaction times.
