Reaction Steps

A solution of 2-nitro-5-bromopyridine (500 mg, 3.15 mmol) in EtOH (15 mL) was treated with methoxyethyl-N-methylamine (1.12 g, 12.6 mmol) and diisopropylethylamine (2.2 mL, 12.6 mmol). The resulting mixture was then heated in a sealed tube at 90° C. for 4 days then cooled and partitioned between EtOAc and water. The organic layer was dried over Na2SO4, filtered and concentrated. The residue was chromatographed on a silica gel column with a 40-100% EtOAc in hexanes gradient to afford the product as a thick yellow oil that crystallized slowly upon standing (270 mg, 41% yield).
