Synthesis of 2, 5-dichloro-N- (3-methvl-benzofdlisozazol-5-vl)- benzenesulfonamide, STX 876 (KRB01030) :; To a solution of 2, 5-dichlorobenzenesulphonyl chloride (105 mg, 0.428 mmol) in dichloromethane (3 mL) was added pyridine (100 pL, 1.02 mmol) and the mixture was stirred under N2 for 5 min, after which time 5-amino-3-methyl-1, 2-benzisoxazole (60 mg, 0.41 mmol) was added. The resulting mixture was stirred for 2 h at room temperature, then saturated NaHCO3 solution (8 mL) was added and the mixture was extracted into ethyl acetate (15 mL). The organic phase was washed with brine, dried (Na2SO4), filtered and evaporated to give a residue that was purified using flash chromatography to afford a yellow solid (100 mg, 68%), single spot at Rf 0.62 (1: 1 hexane: ethyl acetate). mp 229.4-230. 0C, HPLC purity 94% (tR 2.18 min in 10% water-acetonitrile).’H NMR (CDC13) : 6 7.89 (1H, d, J=2.2 Hz), 7.43 (4H, m), 7.22 (1H, m), 7.09 (1H, s, N-H), 2.54 (3H, s).
