YieldReaction ConditionsOperation in experiment
97% With sulfuric acid; at 10℃;Reflux; Comanic acid (50 g, 0.357 mol) was dissolved in MeOH (1 L) and cooled to < 10C. Conc. H2S04 (10 mL)was added dropwise and then the whole refluxed overnight. The volatiles were concentrated in vacuo andthe residue poured into excess iced water. The mixture was extracted with DCM (3x250 mL). The combined organic layer was washed with NaHCO3 solution, brine, dried (Na2SO4) and concentrated in vacuo to yield crude, which was triturated with hexane to give 4-oxo-pyran-2-carboxylic acid methyl ester (50 g, 97%) as solid.
