Reaction Steps

To a solution of 3-[2-chloro-5-(2,3,4,5-tetrahydro-1H-1-benzoazepin-1-ylsulfonyl)-phenyl]-5-ethoxycarbonyl-7-methyl-1,3-dihydro-2H-imidazo[4,5-b]pyridin-2-one (87 mg) in tetrahydrofuran (1.6 mL) was added diisobutylaluminium hydride (0.99 mol/L toluene solution, 0.65 mL) under ice-cooling, and the mixture was stirred at room temperature overnight. To the reaction mixture was added 1 mol/L hydrochloric acid, and the resulting mixture was extracted with ethyl acetate. The extract was washed with brine, and dried over anhydrous magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by column chromatography on silica gel (eluent: n-hexane−ethyl acetate) to give the title compound (63 mg).
