Reaction Steps

To a solution of 3-Iodo-1-triisopropylsilanyl-1H-pyrrolo[2,3-b]pyridine (96, 99 mg, 0.25 mmol) in tetrahydrofuran (5 ml) at −20° C. under nitrogen was added 2.0M solution isopropylmagnesium chloride in tetrahydrofuran (0.2 ml, 0.31 mmol). The reaction mixture was stirred for 1.5 hours, then allowed to warm to 5° C. After the reaction mixture was cooled down to −20° C., a solution of (4-Chloro-benzyl)-(4-chloro-5-formyl-thiazol-2-yl)-carbamic acid tert-butyl ester (95, 80 mg, 0.2 mmol) in tetrahydrofuran (5 mL) was slowly added. The reaction mixture was stirred for 2.5 hrs, then allowed to warm to 5° C. The reaction mixture was poured into iced water, extracted with ethyl acetate, washed with brine, and dried over magnesium sulfate. After removal of solvent, the residue was purified by silica gel column chromatography eluting with ethyl acetate in hexane to provide the compound as an off-white solid (97, 76 mg, 50%). MS (ESI) [M+H+]+=661.32, 663.32.
