実験手順

To a solution of ethyl 4-[4-chloro-2-[(3,5-dichlorophenyl)amino]-7-(1-ethylpropyl)-1H-benzimidazol-1-yl]butanoate (250 mg, 0.50 mmol) in tetrahydrofuran (5 mL) was added lithium borohydride (33 mg, 1.51 mmol) portionwise at 0° C. The mixture was warmed to room temperature and stirred for 36 hr. Water was added and the resulting precipitate was collected by filtration to afford the title compound (213 mg, 0.469 mmol, 94%) as a colorless solid.
