A solution of di-tert-butyl 1-(1-(3-fluorobenzyl)-2-{[(3-fluorobenzyl)oxy]carbonyl}-1H-pyrrolo[3,2-b]pyridin-5-yl)hydrazine-1,2-dicarboxylate (0.33 g, 0.54 mmol, from Step 2) in AcOH (10 mL) was heated in portions, in the microwave, to 180° C. for 10 minutes each. The reactions were pooled and AcOH was removed in vacuo. The residue was dissolved in methanol (2 mL) and 1.0 M NaOH in water (10 mL, 10 mmol) was added. When the hydrolysis reaction was complete, it was filtered, diluted with MeCN and H2O and then purified via preparative HPLC-MS (C18 eluting with a gradient of MeCN/H2O containing 0.15% NH4OH). Yield: (0.17 g, 97%). LCMS (M+H)+: 325.3.
