반응 단계

Dissolve 4-(3-chloro-indazole-1-sulfonyl)-N-(4-fluoro-benzyl)-benzamide (91 mg, 0.20 mmol) in morpholine (1.0 mL) and stir at 100° C. overnight. Dilute the solution with EtOAc (30 mL) and wash with 1N HCl (11 mL), water (10 mL), and satd NaHCO3 (10 mL). Dry, filter and concentrate the organic solution and purify the residue by flash chromatography, using a linear gradient of 20% to 80% EtOAc/hexanes, to give the title compound as a white foam (17 mg, 34%). MS (ES) 495.0 (M+1)+, 493.1 (M−1)−.
