실험 절차

A solution of 2-amino-6-(isopropylamino)benzonitrile sulfamide (Example 90a) (0.14 g, 0.54 mmol) and NaOH (2 N, 0.54 mL) in EtOH (3 mL) was stirred at 90° C. under nitrogen for 0.5 hour. The reaction mixture was cooled to room temperature, and concentrated under vacuum. H2O (1 mL) was added and the reaction mixture was neutralized to pH˜3 with 10% AcOH. The resultant precipitate was extracted with EtOAc, and after evaporation of solvents the residue was purified by preparative thin layer chromatography using a DCM/EtOAc (4:1) solution as eluant, to give N5-isopropyl-1H-benzo[c][1,2,6]thiadiazine-4,5-diamine-2,2-dioxide (0.02 g). 1H NMR (400 MHz, DMSO-d6) δ 1.11 (d, J=6.4 Hz, 6H), 1.84 (bs, 1H), 5.24 (bs, NH), 6.22-6.19 (m, 2H, NH), 7.09 (t, J=8.0 Hz, 1H), 7.48 (bs, 2H). MS 255 (MH+).
