실험 절차

A solution of benzo[1,2,5]thiadiazole-4-sulfonic acid [5-nitro-2-(piperidine-1-carbonyl)-phenyl]-amide (EXAMPLE 2; 90 mg, 2.0 mmol) was dissolved in 1:1 EtOAc/DCM (10 mL), and SnCl2.2H2O (2.3 g, 10 mmol) was added. The mixture was stirred overnight at ambient temperature then concentrated in vacuo. The resulting oil was suspended in DCM and neutralized by shaking with aqueous NaHCO3. The organic layer was dried (MgSO4), filtered, and concentrated in vacuo to afford the title compound (69 mg, 1.7 mmol, 82%). TLC (silica gel, 3:1 EtOAc/hexanes): Rf=0.42. MS (ESI): m/z 418 [M+H]+, 440 [M+Na]+. HPLC (reversed-phase): RT=8.15 min (single peak). 1H NMR (400 MHz, CDCl3): (rotameric broadening) 9.80 (s, 1H), 8.40 (dd, J=8.8 Hz, 1.0 Hz, 1H); 8.15 (dd; J=7.0 Hz, 1.0 Hz, 1H), 7.82 (dd, J=8.8 Hz, 1.0 Hz, 1H), 6.77 (d, J=8.4 Hz, 1H), 6.74 (d, J=2.2 Hz, 1H), 6.19 (dd, J=8.4 Hz, 2.3 Hz, 1H), 5.75 (d, J=2.3 Hz, 2H), 2.96 (bs, 4H), 1.45 (bs, 2H), 1.24 (bs, 4H).
