실험 절차
A solution of 3-benzothienylacetic acid (5.2 mmol) in 10 mL of anhydrous THF was slowly added to a stirred solution of LAH (10.4 mmol) in 50 mL of THF at 0° C. The ice bath was removed and the solution was stirred overnight, while it was allowed to warm to room temperature. The reaction was quenched by addition of water, 10% aqueous NaOH. The mixture was filtered over Celite and the filtrate was concentrated to give 2-(benzo[b]thiophen-3-yl)ethanol, which was used for tosylation.
