Reaction Conditions

Reaction Steps

To a stirred solution of methyl 2-aminonicotinate (1.3 g, 8.54 mmol) and methyl propionate (20.08 mL, 214 mmol) in THF (20 mL) was added sodium 2-methylpropan-2-olate (2.053 g, 21.36 mmol) portionwise over 1 min. The reaction was stirred at rt for 40 min and at 100° C. for 4 h. After this time the reaction was cooled to rt and evaporated in vacuo. The resulting solid was dissolved in water (20 mL) and neutralized to pH 7 with 1.0M aqueous HCl. The resulting solid was filtered and dried under vacuum overnight to give 3-methyl-1,8-naphthyridine-2,4-diol as a tan solid. Mass Spectrum (ESI) m/e=177.2 (M+1).
