Procedure

3-Aminophenol (0.29 g, 2.65 mmmol) and N-(3-aminophenyl)acetamide (0.49 g, 2.65 mmol) in pyridine were treated with 9-oxo-9H-fluorene-2,7-disulfonyl dichloride (1.00 g, 2.65 mmol) in one portion at 0° C. The mixture was allowed to warm to ambient temperature and stirred for 1 hour after which the volatiles were evaporated under reduced pressure. The residue was partitioned between ethyl acetate and H2O. The separated organic phase was washed with 1N HCl, brine, dried (Na2SO4), filtered, and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography (85% ethyl acetate/hexanes) to provide the title compound as a yellow solid (577 mg, 39% yield). 1H NMR (300 MHz, DMSO-d6) δ 9.91 (bs, 1H), 9.47 (s, 1H), 7.9-8.1 (m, 6H), 7.48 (m, 1H), 7.26 bd, 1H), 7.12 (t, 1H), 6.99 (t, 1H), 6.75 (m, 1H), 6.58 (t, 1H), 6.52 (dd, 1H), 6.42 (dd, 1H), 1.98 (s, 3H); MS (ESI) 562 (M−H)−.
