Reaction Steps
13.6 g (244 mmol) of iron powder and 10.5 g (40 mmol) of N-(2-nitrophenyl)benzo[d][1,3]dioxol-5-ylamine were added to a solvent mixture of ethyl acetate (130 ml), water (65 mL) and acetic acid (15 mL), and the mixture was stirred for 1 hour at 70° C. The reaction solution was cooled to room temperature, and the waste was separated by filtration using a filter aid. The organic layer of the filtrate was batched off, washed with water, dried over anhydrous magnesium sulfate, and concentrated under reduced pressure to obtain 9.2 g (yield: 99%) of N-(benzo[d][1,3]dioxol-5-yl)benzene-1,2-diamine as white crystals.
