Procedure
To a solution of isopropyl [4-chloro-2-[(4-chloro-2-methoxy-6-methylphenyl)amino]-7-(1-ethylpropyl)-1H-benzimidazol-1-yl]acetate (Reference Example 11; 861 mg, 1.75 mmol) in methanol (5 mL) was added 8N aqueous sodium hydroxide (1.5 mL), and the mixture was stirred at room temperature for 15 hr. Water was added to the reaction mixture, followed by neutralization with 6N hydrochloric acid. The mixture was concentrated in vacuo, and the residue was dissolved in methanol. The precipitate was removed by filtration, and the filtrate was concentrated in vacuo to give the title compound (781 mg, 1.73 mmol, 99.1%) as an amorphous.
