Participants

Reaction Steps

A solution of methyl 3-[(2-aminoethyl)amino]pyridine-2-carboxylate (3.9 g, 18.6 mmol) in CHCl3 (25 mL) was treated with pyridine (3 mL, 37.3 mmol) then 1-{[(benzyloxy)carbonyl]oxy}pyrrolidine-2,5-dione (Aldrich, 5.57 g, 22.3 mmol) for ½ hr. The reaction was quenched with water and extracted three times with CHCl3. The organic layer was dried with Na2SO4, filtered and evaporated to give an oil. The crude was purified on silical gel using an ISCO normal phase system and eluting with a gradient of 50% to 90% EtOAc Hexanes. The clean fractions were combined to give the product as an oil.
