Reaction Steps
5-(1,3-Dioxolan-2-yl)-2,3-pyridinedicarboxylic acid, dimethyl ester (2.86 g, 0.011 mol) in methanol is added dropwise to a mixture of potassium hydroxide (1.26 g, 0.022 mol) and methanol. The reaction mixture is heated for 3 hours and 30 minutes at about 62° C., cooled to room temperature, acidified to pH 1 with concentrated hydrochloric acid, filtered through diatomaceous earth and the filtrate is concentrated in vacuo to yield the title compound as a pale yellow powder (2.86 g, 100%), identified by IR and NMR spectral analyses.
