An efficient synthesis of 2-pyrrolidinone and N-methyl-2-pyrrolidinone was developed in which the compounds can be labeled with tritium at either the 3-and 4-positions or the 4-position of the lactam ring. Cyclization of [2 3-3Hl-yarninobutyric acid (GABA) yielded [ 3, $-$I -2pyrrolidinone and cycli
At 173 K, the ®ve-membered ring of the title compound, C 22 H 26 N 2 O 5 , has an envelope conformation. The amine group is involved in both intramolecular and intermolecular hydrogen bonds, the latter linking the molecules into centrosymmetric dimers. ## Experimental The title compound was prepa
