Reaction Conditions

Reaction Steps

To a stirred suspension of 2-(methylaminomethyl)quinoxaline (1.10 g, 6.35 mmol) and potassium carbonate (0.88 g, 6.35 mmol) in 2:1 acetonitrile/ethanol (40 mL) was added 1-(4-nitrophenoxy)-3-iodopropane (1.95 g, 6.35 mmol). The resulting mixture was heated at 85° C. overnight, concentrated, and partitioned between ethyl acetate and 10% aqueous potassium carbonate. The organic phase was dried (MgSO4), decolorized (charcoal), and concentrated to afford 1.86 g (83%) of product as a yellow semi-solid which was of sufficient purity to use in the next step.
