Versuchsvorschrift

Dissolve 4-(3-chloro-indazole-1-sulfonyl)-N-(4-fluoro-benzyl)-benzamide (91 mg, 0.20 mmol) in piperidine (1.0 mL) and stir at 90° C. overnight. Dilute the solution with EtOAc (30 mL) and wash with 1N HCl (15 mL) and satd NaHCO3 (15 mL). Dry, filter and concentrate the organic solution and purify the residue by flash chromatography, using a linear gradient of 100% hexanes to 50% EtOAc/hexanes, to give the title compound as a light yellow foam (7 mg, 7%). MS (ES) 493.0 (M+1)+, 491.2 (M−1)−.
