Reaction Steps
To solution containing 4-(2-chloro-6,7-dihydropyrido[3,2-b]thieno[2,3-d]oxepin-9-yl)-5-(2,4-difluorophenyl)-2H-1,2,3-triazole (0.085 g, 0.20 mmol), zinc cyanide (47.9 mg, 0.408 mmol;), and tetrakis(triphenylphosphine)palladium(0) (11.8 mg, 0.0102 mmol;) in N,N-dimethylformamide (2.83 mL, 36.6 mmol;) was evacuated then back-filled with nitrogen. The reaction mixture was heated in microwave to 200° C. for 10 min. The reaction mixture was quenched with sat. NH4Cl then extracted EtOAc (3×). The crude product was purified by column chromatography (EtOAc/Hex) to give 367 (84% yield). MS: (ESI+)=408.2
