Reaction Steps
A mixture of 1-butanol (48 mL), toluene (32 mL), and 1,2-dihydroxy-l-cyclobutene-3,4-dione (16.0 g, 0.1402 mole) was heated at reflux under a nitrogen atmosphere with stirring under a Dean-Stark water separator until water stopped passing over. The resulting solution of the title compound was cooled to 0°-5° C.
