Reaction Steps
A solution of dimethyl 5-dimethoxymethylpyridine-2,3-dicarboxylate (6.57 g, 0.024 mol) in 2N HCl (15 mL) and tetrahydrofuran (25 mL) is stirred at reflux temperature for 2 hours. The tetrahydrofuran is removed in vacuo, the aqueous solution is diluted with water (to 30 mL) and extracted with methylene chloride. The combined methylene chloride extracts are dried over anhydrous magnesium sulfate and concentrated in vacuo to yield the title compound (4.51 g, 82%) as a yellow solid, mp 75°-77° C., identified by IR and NMR spectral analyses.
