実験手順

A mixture of 5-acetyl-2-ethyl-3-(4-{2-[({[(4-methylphenyl)sulfonyl]amino}carbonyl)amino]ethyl}phenyl)benzimidazole (Example 78, 43 mg, 0.085 mmol), p-toluenesulfonic acid (16.2 mg, 0.085 mmol) in ethanol (0.1 ml) was stirred at room temperature for 16 h. The precipitated crystalline solids were filtered, washed with ethanol (0.05 ml×5), and dried in vacuo at 40° C. for 2 h to afford 54 mg (91%) of the title compound as white solids.
