실험 절차
A 4:1 mixture of 3-acetamido-4-hydroxyphthalic acid and 2-methyl-4,5-benzoxazoledicarboxylic acid in acetic anhydride and concentrated sulfuric acid (0.10 mL) is stirred for 18 hours at 110° C., cooled and filtered. The white solid filter cake is air dried to give the title product, 5.39 g (77.1%), identified by NMR and IR spectral analyses.
