Reaction Steps

The 2-(bromomethyl)quinoxaline (3.0 g, 13.4 mmol) was added portionwise to a stirring solution of methylamine (30%) in ethanol (100 mL) at 0° C. The reaction was stirred at 0° C. for 2 hours, concentrated, and partitioned between 10% aqueous potassium carbonate/ethyl acetate. The organic phase was dried (MgSO4), decolorized (charcoal) and concentrated. Purification was accomplished by eluting the sample through a short silica plug to yield 1.80 g (78%) of a brown oil.
