Procedure

To a solution of 4-benzoylamino-naphthalene-1-sulfonyl chloride (320 mg, 0.93 mmol) in CH2Cl2 (20 mL) was added triethylamine (0.26 mL, 1.85 mmol) and m-anisidine (137 mg, 1.11 mmol). The resultant solution was stirred at 25° C. overnight. The reaction mixture was quenched with water and extracted with CH2Cl2. The organic extracts were combined, washed with brine, dried over Na2SO4, filtered and concentrated to provide the crude product as yellow viscous oil. HPLC purification of the residue gave the title compound (190 mg) as a pale white solid. 1H NMR (300 MHz, DMSO) δ 8.72 (d, 1H), 8.26 (d, 1H), 8.15 (d, 1H), 8.02 (d, 2H), 7.78 (d, 1H), 7.60 (m, 5H), 7.00 (t, 1H), 6.55 (m, 2H), 6.46 (d, 1H), 3.56 (s, 3H); LC/MS m/z 433 (M+H)+.
