To 1-benzenesulfonyl-3-iodo-5-methoxy-1H-pyrrolo[2,3-b]pyridine (575, 0.326 g, 0.000788 mol) in tetrahydrofuran (3.00 mL) at −45° C. under nitrogen, isopropylmagnesium chloride (2.0 M in tetrahydrofuran, 0.380 mL) was added slowly. The reaction was allowed to warm to −25° C. in 30 minutes, and then cooled to −45° C. followed by adding (6-fluoro-5-formyl-pyridin-2-yl)-(6-trifluoromethyl-pyridin-3-ylmethyl)-carbamic acid tert-butyl ester (565, 80.0 mg, 0.20 mmol, prepared as described in Example 60, Scheme 176) in tetrahydrofuran (1.0 mL). The reaction was allowed to warm to room temperature 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 20% to 100% ethyl acetate in hexane to give the desired compound (576, 0.080 g, 60%). MS (ESI) [M+H+]+=688.1.
