Sodium borohydride → N-(4-Chloro-2-[1,2,3]triazolo[4,5-b]pyridin-1-yl-phenyl)-4-(1-hydroxy-ethyl)-benzenesulfonamide

Participants

Reaction Steps

To 4-acetyl-N-(4-chloro-2-[1,2,3]triazolo[4,5-b]pyridin-1-yl-phenyl)-benzene-sulfonamide (synthesized according to general procedures F and G, 500 mg, 1.17 mmol) in MeOH (5 mL) was added NaBH4 (144 mg, 3.81 mmol) at 0° C. and the mixture was stirred for one hour at room temperature. The reaction mixture was then diluted with EtOAc (50 mL) and the organics were washed with saturated aqueous NH4Cl (50 mL), water (50 mL), and brine (50 mL). The organics were subsequently dried (Na2SO4), concentrated in vacuo, and purified by automated flash chromatography to obtain the title compound as foamy white solid (424 mg) in 84% yield: MS (ES) M+H expected 430.1, found 430.1.
