3-Methyl-5-benzofuranol was prepared by a one-pot process from morpholine, propionaldehyde, and p-benzoquinone in 85–87% isolated yields. Avoiding the tedious multistep isolation and purification operations, this practical and efficient process dramatically enhanced the production efficiency as well as reduced the amount of chemical wastes of reaction. The scale-up results showed that the performance
