Procedure

4-Hydrazinocarbonyl-1-(2,2,6,6-tetramethyl-4-piperidinyl)-2-pyrrolidone was prepared by the hydrazinolysis of 4-(methoxycarbonyl)-1-(2,2,6,6-tetramethyl- 4-piperidinyl)-2-pyrrolidone with excess hydrazine hydrate in methanol. The above intermediate half ester was prepared by the addition of 4-amino-2,2,6,6-tetramethylpiperidine to dimethyl itaconate according to the procedure described in U.S. Pat. No. 4,309,546.
