Reaction Steps

Phosphoryl trichloride (17.3 ml) was added to a solution of dimethyl 2-ethyl-6-hydroxypyridine-3,5-dicarboxylate (22.3 g) in acetonitrile (250 mL) at room temperature. The mixture was stirred at 90° C. under nitrogen atmosphere for 3 hours. The mixture was neutralized with aqueous saturated sodium hydrogen carbonate solution at 0° C. and extracted with ethyl acetate. The organic layer was separated, washed with water and brine, dried over anhydrous magnesium sulfate and concentrated in vacuo to give the title compound (24.0 g).
