Isoquinoline-1-carbaldehyde → HCID 58778962, compound

Participants

Reaction Steps

In ethanol (13 ml), isoquinoline-1-carbaldehyde (500 mg, 3.18 mmol) and methyl 4-amino-2-fluoro-3-hydroxyphenylacetate (632 mg, 3.17 mmol) were stirred at room temperature for 2 days. Iodobenzene diacetate (1.23 g, 3.82 mmol) was added, and the reaction mixture was stirred at room temperature for 10 minutes. The reaction mixture was distilled under reduced pressure to remove the solvent. The residue was purified by chromatography on a silica gel column, whereby from n-hexane/ethyl acetate (3:1, v/v) eluate fractions, methyl (7-fluoro-2-(1-isoquinolinyl)-6-benzoxazolyl)acetate (155 mg, 14%) was obtained as a red brown solid.
