Ammonium Chloride → tert-butyl (+/-)-[(4aR*,8aS*)-8a-(6-amino-2,2-difluorobenzo[1,3]dioxol-4-yl)-4,4a,5,6,8,8a-hexahydro-7-oxa-3-thia-1-azanaphthalen-2-yl]carbamate

참여 물질

반응 단계

Iron powder (7.09 mg) and a saturated ammonium chloride solution (1.0 ml) were added to a solution of tert-butyl (±)-[(4aR*,8aS*)-8a-(2,2-difluoro-6-nitrobenzo[1,3]dioxol-4-yl)-4,4a,5,6,8,8a-hexahydro-7-oxa-3-thia-1-azanaphthalen-2-yl]carbamate (60.0 mg) in ethanol (20 ml), and the mixture was heated under reflux for 30 minutes. The reaction solution was returned to room temperature and the insoluble matter was removed by filtration through celite. The solvent was evaporated under reduced pressure and the residue was purified by silica gel column chromatography to obtain the title compound (50.0 mg).
