Reaction Steps

A degassed mixture of 1-benzyl-5-chloro-1H-pyrrolo[3,2-b]pyridine-2-carbonitrile (0.12 g, 0.45 mmol, from Step 3), di-tert-butyl hydrazine-1,2-dicarboxylate (0.12 g, 0.54 mmol, Aldrich), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine-(2′-aminobiphenyl-2-yl)(chloro)palladium (1:1) (35 mg, 0.045 mmol, Aldrich) and Cs2CO3 (0.18 g, 0.54 mmol, Aldrich) in toluene (2.5 mL) was heated at 100° C. for 3 hours. Upon cooling to room temperature, the reaction mixture was diluted with DCM, filtered to remove solids, and the solvent was removed in vacuo. Flash chromatography, eluting with a gradient from 0-20% EtOAc in hexanes afforded purified product. Yield: (0.14 g, 67%).
