실험 절차

In ethanol (15 ml), 6-fluoro-1-methylindole-3-carbaldehyde (500 mg, 2.82 mmol) and methyl 4-amino-3-hydroxyphenylacetate (767 mg, 4.23 mmol) were stirred at room temperature for 2 hours. Iodobenzene diacetate (1.09 g, 3.38 mmol) was added and the mixture was stirred at room temperature for 1 hour. The reaction mixture was then distilled under reduced pressure to remove the solvent. The residue was purified chromatography on a silica gel column, whereby from n-hexane-ethyl acetate (1:1, v/v) eluate fractions, methyl (2-(6-fluoro-1-methyl-3-indolyl)-6-benzoxazolyl)acetate (889 mg, 93%) was obtained as a brown solid.
