실험 절차
To a solution of [5-(2-methyl-1,3-dioxolan-2-yl)thien-2-yl]methanol prepared in the above step in THF (240 ml) was added 1N hydrochloric acid (48 ml) and the mixture was stirred for 2 hours at room temperature. Thereto was added sodium hydrogencarbonate (4.04 g) and the mixture was extracted with ethyl acetate. The organic layer was washed with a saturated aqueous sodium chloride solution and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure to give 1-[5-(hydroxymethyl)thien-2-yl]ethanone. This product was used in the next step without purification.
