Reaction Steps
To a 100-mL round-bottomed flask was added 3-((2-methoxy-3-pyridinyl)methyl)-2,5-piperazinedione (398 mg, 1.69 mmol) and borane methyl sulfide, complex (0.64 mL, 6.77 mmol, Aldrich, St. Louis, Mo.) in THF (10 mL). The reaction mixture was stirred at 70° C. for 2 h. The mixture was cooled to room temperature, diluted with MeOH (1 mL), followed by 1N NaOH (12 mL), and extracted with DCM (2×50 mL). The organic extract was washed with saturated NaCl (20 mL) and dried over Na2SO4. The solution was filtered and concentrated in vacuo to give the crude 2-((2-methoxy-3-pyridinyl)methyl)piperazine as colorless viscous oil, which was used without purification.
