실험 절차

In a round bottomed flask dissolve 1-[5-tert-butyl-2-(2-hydroxy-ethyl)-2H-pyrazol-3-yl]-3-{4-[7-(4-methanesulfonyl-phenyl)-imidazo[1,2-a]pyridin-3-yl]-benzyl}-urea (0.2 g, 0.34 mmol) and triethyl amine (0.48 mL, 10 equiv.) in DCM (20 mL) under N2. Add methanesulfonyl chloride (0.13 mL, 4.8 equiv.) dropwise and stir the reaction at room temperature for 15 minutes. Load the crude reaction directly onto silica gel and purify (EtOAc to 5% MeOH: DCM) to give a yellow solid (0.22 g, 97%). MS (ES), m/z 665 (M+1).
