Reaction Steps

To a 100-mL round-bottomed flask was added ethyl glycyl-3-(2-methoxy-3-pyridinyl)alaninate (1.018 g, 3.62 mmol) and N,N-diisopropylethylamine (0.63 mL, 3.62 mmol) in MeOH (20 mL). The reaction mixture was stirred at 70° C. for 36 h. The solvent was partially removed under a vacuum and the solid formed was filtered, washed with MeOH and dried to give 3-((2-methoxy-3-pyridinyl)methyl)-2,5-piperazinedione (0.732 g) as a white solid.
