実験手順

3-({[tert-Butyl(diphenyl)silyl]oxy}methyl)benzyl 1-[3-({[tert-butyl(diphenyl)silyl]oxy}methyl)benzyl]-5-chloro-1H-pyrrolo[3,2-b]pyridine-2-carboxylate (2.18 g, 2.38 mmol, from Step 3) and di-tert-butyl hydrazine-1,2-dicarboxylate (0.71 g, 3.1 mmol, Aldrich), dicyclohexyl(2′,4′,6′-triisopropylbiphenyl-2-yl)phosphine-(2′-aminobiphenyl-2-yl)(chloro)palladium (1:1) (0.22 g, 0.28 mmol, Aldrich) and Cs2CO3 (0.91 g, 2.8 mmol) were combined in toluene (27 mL) and the mixture was degassed by a stream of nitrogen bubbled through the solution for 10 minutes. The reaction vessel was sealed and heated at 110° C. for 3 hours. The reaction mixture was partitioned between water and ethyl acetate, the aqueous layer was extracted three times and the combined organic extracts were dried over sodium sulfate, filtered and concentrated. The product was purified by flash chromatography, eluting with a gradient from 0-25% EtOAc/hexanes. Yield: (1.31 g, 50%).
