Reaction Steps

2-Amino-4-nitrophenol (10 g, 0.065 mol) was dissolved in tetrahydrofuran (100 ml) and, after cooling to 0° C., acetic anhydride (12.24 ml, 0.130 mol) was added dropwise, followed by stirring at room temperature for 2 h. Thereafter, methanol (10 ml) was added to the reaction mixture, which was then stirred at room temperature for 30 min and, thereafter, the solvent was evaporated and the resulting residue was diluted with diethyl ether and filtered. The solvent was evaporated off the filtrate and the resulting solids were dried to yield the end compound 2-acetamido-4-nitrophenol (12.21 g) as a pale brown solid mass.
