Reaction Steps

To a 100-mL round-bottomed flask was added ethyl glycyl-3-methoxyphenylalaninate trifluoroacetate (598 mg, 2.13 mmol), Hünig's base (0.371 mL, 2.13 mmol), and MeOH (20 mL). The reaction mixture was stirred at 75° C. for 24 h. The mixture was allowed to cool to room temperature. The solid formed was collected by filtration and washed with MeOH to give 3-(3-methoxybenzyl)-2,5-piperazinedione (423 mg).
