Methanol → N-(1-(2-(4-chlorophenyl)-1-hydroxybutan-2-yl)-1H-indazol-4-yl)-N-((2-(trimethylsilyl) ethoxy)methyl)methanesulfonamide

Participants

Reaction Steps

To a suspension of LiBH4 (120 mg, 5.43 mmol) in THF (5 mL) was added MeOH (174 mg, 5.43 mmol) and a solution of methyl 2-(4-chlorophenyl)-2-(4-(N-((2-(trimethylsilyl)ethoxy)methyl)methylsulfonamido)-1H-indazol-1-yl)butanoate (600 mg, 1.09 mmol) in THF (8 mL) followed. The mixture was stirred at room temperature for 2 h. The solution was quenched with saturated NH4Cl solution, and extracted with ethyl acetate (30 mL). The organic layer was washed with brine, dried over sodium sulfate, filtered and evaporated. The residue was purified by silica gel chromatography (PE/EA=3/1) to afford the title compound as a pale yellow solid. LC/MS m/z=524.2 [M+H]+.
