Ethyl(5-methoxy-1-benzofuran-3-yl)acetate → 2-(5-Methoxy-1-benzofuran-3-yl)ethanol

Participants

Reaction Steps

To a stirred suspension of LiAlH4 (200 mg, excess) in THF at 0° C., ethyl(5-methoxy-1-benzofuran-3-yl)acetate (1.17 g, 5 mmol) in THF (20 ml) was added slowly. After the addition, reaction mixture was stirred at room temperature for 1 hr and quenched with saturated NH4Cl solution. The product was extracted with chloroform and washed well with water. It was dried over anhydrous MgSO4, filtered and concentrated. The product, 2-(5-methoxy-1-benzofuran-3-yl)ethanol, was obtained as a white oil and was pure enough to be taken to the next step without purification, yielding a yellow oil. Yield: 900 mg (93%); (M+H): 193.
