実験手順

A mixture of tert-butyl(2-{2-[(2,4-dichlorophenyl)carbonyl]-7-(diethylamino)-1H-benzimidazol-1-yl}ethyl)carbamate (Reference example 224, 395 mg, 0.781 mmol) and hydrochloric acid (10%, methanol solution, 2 mL) in methanol (2 mL) was stirred at room temperature for 14 h and at 50° C. for 2 h. The mixture was diluted with aqueous sodium hydrogen carbonate and extracted with ethyl acetate. The combined organic layer was washed with brine, dried over sodium sulfate, filtered and concentrated in vacuo. The residue was purified by column chromatography on silica gel eluting with a 10-30% ethyl acetate/n-hexane gradient mixture to give a yellow amorphous solid (258 mg, 0.666 mmol, 85%).
