반응 단계
A mixture of 7-methoxy-9-oxoxanthene-2-carboxylic acid in ethanol (100ml) and concentrated sulfuric acid (10 ml) was refluxed under nitrogen for 24 hours. The reaction mixture was concentrated and cooled. The product, which precipitated, was filtered off and recrystallized from ethanol to give white crystals (2.53g, 84%), mp. 170°-172° C.
