Methanol → (4-Bromo-1-benzofuran-2-yl)methanol

Participants

Reaction Steps

To a solution of 4-bromo-2-ethoxycarbonylbenzo[b]furan (0.5 g) in tetrahydrofuran (5 ml) was slowly added sodium borohydride (0.21 g) at room temperature. After 5 minutes, methanol (0.5 ml) was added thereto dropwise. The reaction mixture was stirred at room temperature for one hour and then ethyl acetate and water were added thereto. The mixture was adjusted to pH 5, and the layers were separated. The organic layer was washed with water and brine, dried over magnesium sulfate and evaporated to afford 4-bromo-2-hydroxymethylbenzofuran (0.36 g).
