Reaction Steps

A solution of methyl 2-[N-(5-bromo-2-propoxybenzyl)-N-ethylamino]pyridine-5-carboxylate (reference example 1) (0.12 g, 0.29 mmol) in THF (3 ml) and methanol (3 ml) was treated with aqueous sodium hydroxide (1N, 1.8 ml). The reaction was heated to 40° C. for 18 hours. The solvent was then evaporated off and the residue diluted with water (3 ml) and acidified with acetic acid (1N, 3 ml). The solid was filtered off to give the title compound (0.1 g, 88%) as a white solid.
