実験手順

0.005 ml of acetic anhydride was added to a pyridine (1 ml) solution of 13.7 mg of 1-(2-(6-(6-amino-pyridin-3-yloxy)-2-pyridin-2-yl-3H-benzimidazol-5-yl)-pyrrolidin-1-yl)-ethanone, and the reaction liquid was stirred at room temperature for 3 hours. The reaction liquid was evaporated away under reduced pressure, the resulting residue was dissolved in 1 ml of trifluoroacetic acid, and the reaction liquid was stirred at room temperature for 3 hours. The reaction liquid was distilled under reduced pressure, and the resulting residue was purified through reversed-phase middle-pressure liquid chromatography [ODS-AS-360-CC (by YMC), mobile phase: water-acetonitrile-0.1% trifluoroacetic acid] and through silica gel column chromatography (developing solvent: chloroform/methanol=9/1) to obtain the entitled compound as an oily substance.
