4-Aminophenol → HCID 14499215, compound

Participants

Reaction Steps

A mixture of 334 mg (1.50 mmol, Aldrich) of 6-bromo-2-naphthol, 218 mg (2.00 mmol, Aldrich) of 4-aminophenol, and 1.0 g of sodium bisulfite in 5 ml of H2O was heated to 150° in a closed Pyrex tube for 76 hours. The reaction was cooled, added to 25 ml of H2O and extracted with 25 ml of ethyl acetate. The organic extract was dried (MgSO4) and concentrated in vacuo to give a solid. The crude solid was purified by flash chromatography (10×5.0 cm, 1: EtOAc/petroleum ether) followed by recrystallization (EtOAc/petroleum ether) to afford 330 mg (70%) of title compound as small grey-white crystals, m.p. 179°-180°.
