실험 절차
A mixture of 5.3 g of methyl 2-methyl-4,5-dinitrobenzoate, 1.06 g of 10% palladium on carbon (50% wet), 53 mL of ethanol, and 53 mL of dioxane was thoroughly stirred at room temperature under a hydrogen atmosphere. The insoluble materials were filtered and washed sufficiently with methanol. The filtrate and the washing liquid were concentrated together, and then dried under reduced pressure to obtain 3.98 g of methyl 4,5-diamino-2-methylbenzoate.
