実験手順
Zinc powder (133 mg) and ammonium formate (320 mg) were added to a solution of (±)-N,N-di(tert-butyloxycarbonyl)-[(4aR*,8aR*)-8a-(4-azidothiophen-2-yl)-4,4a,5,6,8,8a-hexahydro-7-oxa-3-thia-1-azanaphthalen-2-yl]amine (503 mg) in methanol (76.2 ml). The mixture was stirred at room temperature overnight, and then the solvent was evaporated under reduced pressure at room temperature or lower. Water was added to the residue, and the aqueous layer was extracted with ethyl acetate. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (325 mg).
