実験手順

To a solution of ethyl 4-{4-chloro-7-(1-ethylpropyl)-2-[(4-methyl-6-pyrrolidin-1-ylpyridin-3-yl)amino]-1H-benzimidazol-1-yl}butanoate (650 mg, 1.27 mmol) in tetrahydrofuran (5 mL) was added lithium borohydride (84 mg, 3.82 mmol) portionwise at 0° C. The mixture was warmed to room temperature and stirred for 24 hr. Aqueous ammonium chloride was added and the mixture was stirred for 30 minutes followed by addition of aqueous sodium bicarbonate. The mixture was extracted with ethyl acetate. Organic layer was washed with brine, dried over anhydrous magnesium sulfate and concentrated in vacuo to give a light brown solid, which was recrystallized from ethyl acetate/isopropyl ether to give the title compound (375 mg, 0.798 mmol, 63%) as a colorless solid.
