Procedure

To a cooled (0° C.) solution of 5-(2,4-difluorophenoxy)-1-isobutyl-1H-indazole-6-sulfonyl chloride (0.20 g, 0.50 mmol) in dichloromethane under N2 atmosphere was added 3-(dimethylamino)propylamine (0.05 g, 0.50 mmol) and triethylamine (0.15 g, 1.5 mmol) drop-wise. The reaction mixture was stirred for 4 hours and then diluted with dichloromethane (20 mL), washed with water, saturated NaHCO3 and brine and then dried over MgSO4. The mixture was concentrated under reduced pressure and chromatographed on preparatory TLC plates eluting with dichloromethane/MeOH/Et3N (95:4:1) to afford the 93 mg of final product (40% yield). MS (APCI−) m/z 466 detected; 1H NMR (400 mHz, CDCl3) δ 8.15 (s, 1H), 7.91 (s, 1H), 7.20 (m, 1H), 7.09 (s, 1H), 7.00 (m, 1H), 6.90 (m, 1H), 4.22 (d, 2H), 3.12 (t, 2H), 2.35 (m, 3H), 2.13 (s, 6H), 1.70 (m, 2H), 0.94 (d, 6H).
