A mixture of 8-amino-2-hydroxynapthalene (50 g, 0.3 mole) and 4-nitrobenzenesulfonyl chloride (55 g, 0.25 mole) in pyridine (500 ml) was heated under reflux for 2.5 hours then allowed to stand O/N. The mixture was poured in ice water and acidified with HOAc. The precipitated product was boiled in hexane and then recrystallized from ethyl acetate-hexane to give 40 g of green product (47%). This material was used in Part B.
