Reaction Steps

In a N2 charged round bottom flask, Sodium Hydride, 60%, (41 mg, 1.01 mmol) was suspended in dimethylformamide (2.5 mL). The solution was maintained under N2 and cooled to 0° C. for 10 minutes. Next, 6-(1-Methyl-1H-pyrazol-4-yl)-1H-pyrrolo[3,2-b]pyridine (200 mg, 1.01 mmol) was dissolved in dimethylformamide (2.5 mL) and added to the cooled solution dropwise. The solution was allowed to stir at 0° C. for an additional 10 minutes. Finally, Bromo-acetic acid ethyl ester (123 uL, 1.11 mmol) was slowly added to the reaction vessel. The reaction was allowed to equilibrate back to room temperature, while stirring for 2 hours. Finally, the solution was transferred to a separatory funnel with dichloromethane (75 mL) and washed with water (2×75 mL). The organic layer was dried over Na2SO4, concentrated down and purified by flash chromatography (0-10% Methanol/dichloromethane step gradient) to afford the title compound (122 mg, 43% yield).
