실험 절차
To a solution of ethyl (E)-3-(2,3-dihydrobenzofuran-5-yl)-2-propenoate (160.0 g, 733 mmols) in acetic acid (960 mL) was added 5% palladium on activated carbon (32.0 g, 50% hydrous). The mixture was stirred at 50° C. for 3.5 hours under hydrogen atmosphere (ambient pressure). The catalyst was filtered off and the filtrate containing 156.7 g (yield: 97%) of the title compound was obtained which was provided to the next step.
