실험 절차

To solution containing 3-(2-chloro-6,7-dihydropyrido[3,2-b]thieno[2,3-d]oxepin-9-yl)-2-(2,4-difluorophenyl)-2H-1,2,4-triazole (0.030 g, 0.072 mmol), zinc cyanide (16.9 mg, 0.144 mmol), and tetrakis(triphenylphosphine)palladium(0) (4.16 mg, 0.00360 mmol) in N,N-dimethylformamide (1.00 mL, 12.9 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) (eluted 50% EtOAc) to give 366 (60% yield). MS: (ESI+)=408.0
