Reaction Steps

A mixture of ethyl 4-(3-(3-bromo-1,2,4-thiadiazol-5-yl)phenyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate (51 mg, 0.092 mmol), tetrakis(triphenylphosphine)palladium(0) (53 mg, 0.046 mmol), and zinc cyanide (107 mg, 0.915 mmol) in DMF (1.0 mL) was heated to 95° C. overnight. The resulting mixture was filtered and concentrated under reduced pressure. Purification by chromatography on silica eluting with 0-50% ethyl acetatehexane gave ethyl 4-(3-(3-cyano-1,2,4-thiadiazol-5-yl)phenyl)-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine-5-carboxylate. LRMS (ESI) calc'd for C24H27N6O3SSi [M+H]+: 507, found 507.
