실험 절차

To a solution of ethyl 4-[4-chloro-2-{[6-(dimethylamino)-4-methylpyridin-3-yl]amino}-7-(1-ethylpropyl)-1H-benzimidazol-1-yl]butanoate (200 mg, 0.41 mmol) in tetrahydrofuran (4 mL) was added lithium borohydride (27 mg, 1.23 mmol) portionwise at 0° C. The mixture was warmed to room temperature and stirred for 24 hr. Water was added and the mixture was extracted with ethyl acetate. Organic layer was washed with brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give a solid, which was recrystallized from ethyl acetate to give the title compound (95 mg, 0.214 mmol, 52%) as a colorless solid.
