실험 절차

Diisobutylaluminum hydride in hexane (1 M, 0.69 mL) was added to a solution of methyl 3-phenyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]-propanoate (150 mg, 0.00031 mol) in DCM (3 mL, 0.05 mol) and the mixture was cooled to −78° C. under a nitrogen atmosphere. The reaction was stirred for 1 h at −78° C. and was allowed to warm to room temperature for 4 hrs. The reaction was quenched with methanol (100 μL), and saturated ammonium chloride (100 μL), and then taken up in ethyl acetate dried over MgSO4 and filtered. The filtrate was concentrated to give 3-phenyl-3-[4-(7-[2-(trimethylsilyl)ethoxy]methyl-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-1H-pyrazol-1-yl]propan-1-ol (130 mg, 92%) as an oil. m/z=450 (M+1).
