1-[(4-Methylphenyl)oxy]pyrrolidine-2,5-dione and 1-[(4-methylphenyl)oxy]piperidine-2,6-dione react in a Lossen-type reaction with primary alcohols in the presence of triethylamine to furnish corresponding N (alpha)-urethane-protected beta-alanine and gamma-aminopropionic acid (GABA), respectively, with excellent yields and purities, in an essentially "one-pot" procedure.
