Participants

Reaction Steps

To a mixed liquid of 6.80 g of methyl 4-(tert-butylamino)-2-(methoxymethyl)-5-nitrobenzoate and 68.0 mL of methanol was added 37.0 mL of 6 M hydrochloric acid, followed by stirring overnight under the heating and refluxing condition. The solvent was evaporated under reduced pressure, and then 111 mL of methanol and 1.00 mL of concentrated sulfuric acid were added thereto, followed by stirring overnight under the heating and refluxing condition. Ethyl acetate and a saturated aqueous sodium hydrogen carbonate solution were added thereto, followed by extraction with ethyl acetate, the organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to obtain 4.73 g of methyl 4-amino-2-(methoxymethyl)-5-nitrobenzoate as a yellow solid.
