Reaction Steps

To a solution of 2-[4-chloro-2-[(4-chloro-2-methoxy-6-methylphenyl)amino]-7-(1-ethylpropyl)-1H-benzimidazol-1-yl]ethanol (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 hours. 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 781 mg (1.73 mmol, 99.1%) of the title compound as an amorphous.
