Reaction Steps

To a suspension of anhydrous aluminum hydride (266 mg, 2.0 mmol, Alfa Aesar) in 5 mL of 1,2 dimethoxyethane at 0° C. was added lithium aluminum hydride (1 M soln. in THF, 1.0 mL, 1.0 mmol). A solution of 2-(4-(2-fluoro-4-nitrophenoxy)-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-oxoethyl formate (72 mg, 0.2 mmol) in 5 mL of 1,2-dimethoxyethane was added dropwise. The reaction mixture was stirred at rt for 2 h and quenched by the addition of 5 mL of cold water. The mixture was extracted with EtOAc (3×30 mL) and the combined organic extracts were dried (MgSO4), concentrated in vacuo and purified by flash column chromatography (ISCO RediSep® silica gel cartridge, etuting with 2–10% MeOH in dichloromethane) to give 1-(4-(4-amino-2-fluorophenoxy)-1H-pyrrolo[2,3-b]pyridin-3-yl)ethane-1,2-diol (27 mg, 45%): MS(ESI+) m/z 304.3 (M+H)+ and 2-(4-(4-amino-2-fluorophenoxy)-1H-pyrrolo[2,3-b]pyridin-3-yl)ethanol (10 mg, 18%): MS(ESI+) m/z 288.3 (M+H)+.
