甲基 3-氨基-2-(甲氨基)苯甲酸甲酯

反应条件: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A solution of 20.7 g (98 mmol) of methyl 2-methylamino-3-nitrobenzoate in 1200 mL of methanol was inerted with nitrogen. To this solution was added 5 g (2.3 mmol) 10% palladium on carbon (50% wet). The reaction was purged with hydrogen and stirred under balloon pressure hydrogen for 7 h. The catalyst was removed by filtration and the filtrate was concentrated in vacuo to give 17.5 g (99%) of the title compound. The reaction was purged with hydrogen The catalyst was removed by filtration the filtrate was concentrated in vacuo

实验步骤: To a suspension of methyl 2-(methylamino)-3-nitrobenzoate (2.10 g, 10.0 mmol) in tetrahydrofuran (40 mL) was added palladium on carbon (210 mg), and the mixture was purged with hydrogen and stirred under balloon pressure hydrogen for 2 hr at room temperature. The catalyst was removed by filtration, and the filtrate was concentrated in vacuo to give the title compound (1.80 g, 10.0 mmol, 100%) as a pale yellow oil. the mixture was purged with hydrogen The catalyst was removed by filtration the filtrate was concentrated in vacuo
