실험 절차

A stirred solution of 2-(1-(4-fluorophenyl)-1H-indazol-5-yloxy)-2-phenylacetamide (137b, 20 mg, 60 μmol) in THF (2 ml) was cooled to 0° C., and potassium 2-methylpropan-2-olate (18.6 mg, 170 μmol) was added. The mixture was stirred at 0° C. for 10 min, and a solution of 2-methylpropanoyl chloride (30 mg, 280 μmol) in THF (0.5 ml) was added. Stirring was continued for 30 min at 0° C. Then the sample was concentrated in vacuo and purified by semi-prep. HPLC go give white solid material, 14 mg (59%).
