2-Aminophenol → HCID 57548517, compound

Participants

Reaction Steps

17.30 g (157 mmol) of 99% strength 2-aminophenol and 17.15 g (209 mmol) of anhydrous sodium acetate are added to a solution of 25.0 g (121 mmol) of 98% strength 2,6-dinitrochlorobenzene in 185 ml of anhydrous ethanol under nitrogen while stirring. The reaction solution is refluxed for 2 hours and subsequently cooled to room temperature. The red-violet crystalline needles are separated off on a “black band” filter, washed with water until the washings are colorless and dried at 50° C. under reduced pressure. This gives 27.90 g (84% of theory) of shiny black needles which melt at 189-192° C. (lit.: 191° C.).
