2-Aminophenol → 2-(4-methoxyphenyl)-1,3-benzoxazole

Participants

Reaction Steps

In an acetic acid solvent in the presence of sodium acetate (NaOAc) (3.0 eq.), a solution including 2-aminophenol (1.0 eq.) and 4-methoxybenzaldehyde (1.0 eq.) was refluxed. After cooling, the reaction mixture was distributed between ethyl acetate and water, and an organic layer was dried, filtered, and evaporated. The residual was purified by silica gel column chromatography using hexane and acetone (25:1) to obtain a solid Compound 124.
