Tetrahydrofuran → HCID 86686814, compound

Participants

Reaction Steps

To a mixture of methyl 2-{-4-[({4-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-6-(morpholin-4-yl)pyrimidin-2-yl}amino)methyl]piperidin-1-yl}cyclopentane carboxylate (50 mg) and tetrahydrofuran (1 mL) were added a 1.01 M solution of (240 μL) diisobutylaluminum in toluene at 0° C., followed by stirring at the same temperature for 6 hours. To the reaction mixture were added methanol and sodium sulfate decahydrate, followed by stirring at room temperature for 1 hour. The insoluble matter was removed by filtration and then concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (hexane:ethyl acetate=50:50-0:100) to obtain desired (2-{4-[({4-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-6-(morpholin-4-yl)pyrimidin-2-yl}amino)methyl]piperidin-1-yl}cyclopentyl)methanol (33 mg).
