| Reactant | 4-Aminophenol | HCID 403 | — |
| Reactant | Dichlone | HCID 8342 | — |
| Solvent | Ethanol | HCID 702 | — |
| Product | 1,4-Naphthalenedione, 2-chloro-3-((4-hydroxyphenyl)amino)- | HCID 260556 | — |
Reaction Steps
2,3-Dichloro-1,4-naphthoquinone (1.0 g, 4.4 mmol) was dissolved in 80 ml ethanol at 60° C., to which p-aminophenol (1.44 g, 13.2 mmol) in 20 ml ethanol was added. The reaction mixture was stirred at room temperature for 16 h. The precipitated product was filtered off and recrystallized from ethanol to afford pure purple crystals. Yield: 1.30 g (99%), Mp: 233° C.
