実験手順
A mixture of 5.3 g of methyl 2-methyl-4,5-dinitrobenzoate, 1.06 g of 10% palladium on carbon (50% water wet), 53 mL of ethanol, and 53 mL of 1,4-dioxane was vigorously stirred at room temperature overnight under a hydrogen atmosphere. The insoluble material was filtered and washed with methanol. The filtrate was concentrated, and then dried under reduced pressure to obtain 3.98 g of methyl 4,5-diamino-2-methyl benzoate.
