実験手順

To a solution of 1-Benzenesulfonyl-5-chloro-3-iodo-1H-pyrrolo[2,3-b]pyridine (581, 4.36 g, 10.4 mmol) in tetrahydrofuran (100.0 mL) at −40° C. under nitrogen, isopropylmagnesium chloride (2.0 M in tetrahydrofuran. 5.06 mL) was added slowly. The reaction was allowed to warm to 5° C. over 60 minutes, then cooled to −40° C., followed by adding 2-methylsulfanyl-pyrimidine-5-carbaldehyde (607, 1.30 g, 8.43 mmol, dissolved in tetrahydrofuran 15.0 mL). The reaction was allowed to warm to 10° C. over 2 hours. The reaction was poured into aqueous ammonium chloride and extracted with ethyl acetate. The organic layer was dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated and purified by silica gel column chromatography eluting with 2% to 15% methanol in dichloromethane to give the desired compound (608, 3.00 g, 79.6%). MS (ESI) [M+H+]+=447.2.
