실험 절차

To a mixture of methyl 2-[(tert-butoxycarbonyl) (prop-2-en-1-yl)amino]pent-4-enoate (5.0 g) produced above and tetrahydrofuran (100 mL) was added 1M diisobutylaluminum hydride/toluene solution (60 mL) at 0° C., and the mixture was stirred at the same temperature for 15 min. The reaction mixture was diluted with aqueous potassium sodium tartrate solution, and the mixture was extracted with ethyl acetate. The extract was dried over anhydrous sodium sulfate. Insoluble material was filtered off, and the filtrate was concentrated under reduced pressure to give the title compound (3.76 g).
