A solution of 4-chloromethylpyridine hydrochloride (0.12 g, 0.73 mmol) in DMF (3 ml) was treated with potassium carbonate (0.29 g, 2.10 mmol). A solution of methyl 2-[N-(5-bromo-2-hydroxybenzyl)-N-ethylamino]pyridine-5-carboxylate (0.26 g, 0.71 mmol) in DMF (4 ml) was added. The reaction was stirred for 24 hours and then the reaction was diluted with water and extracted with ethyl acetate (×3). The organic phases were combined and washed with water and brine once, dried (MgSO4) and evaporated. Chromatography eluant: ethyl acetate/hexane gave methyl 2-[N-(5-bromo-2-(4-pyridylmethoxy)benzyl)-N-ethylamino]pyridine-5-carboxylate as a white solid (0.209 g, 65%).
