Reaction Steps
A degassed mixture of 5-chloro-1-(phenylsulfonyl)-2-(trifluoromethyl)-1H-pyrrolo[3,2-b]pyridine (0.500 g, 1.39 mmol, from Step 2), di-tert-butyl hydrazine-1,2-dicarboxylate (0.35 g, 1.5 mmol, Aldrich), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine-(2′-aminobiphenyl-2-yl)(chloro)palladium (1:1) (0.13 g, 0.16 mmol, Aldrich) and Cs2CO3 (0.50 g, 1.5 mmol) in toluene (11.5 mL) was heated at 110° C. for 2 hours. After cooling to room temperature, water was added, and the aqueous layer was extracted with three portions of EtOAc. The combined organic extracts were dried over sodium sulfate, filtered and concentrated. The product was purified by flash chromatography, eluting with a gradient from 0-50% EtOAc in hexanes. (Yield: 0.66 g, 86%).
