Reaction Steps

To a solution of 4-aminophenol (4.5 g) in dioxane (20 ml) was added dropwise a solution of 1-naphthalenesulfonyl chloride (4.4 g) in dioxane (20 ml). The mixture was further stirred at room temperatue for 4.5 hours and poured into water. The precipitate was collected by filtration, recrystallized from ethanol and decolored with activated carbon to give N-(ρ-hydroxyphenyl)-1-naphthalenesulfonamide (4.2 g), mp 195-196° C.
