反応手順

To a stirred suspension of LiAlH4 (200 mg, excess) in THF at 0° C., ethyl(-1-benzofuran-3-yl)acetate (1.02 g, 5 mmol) in THF (20 mL) was added slowly. After the addition, the 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-(1-benzofuran-3-yl)ethanol obtained as a white oil was pure enough to be taken to next step without further purification. Yield: 800 mg (98%); (M+H): 163.
