PROCEDURE
实验过程
A solution of (S)-tert-butyl 3-((6-bromo-1,7-naphthyridin-8-yl)amino)pyrrolidine-1-carboxylate (1141 mg, 2.9 mmol), zinc cyanide (681 mg, 5.80 mmol) and N1,N1,N2,N2-tetramethylethane-1,2-diamine (87 μL, 0.580 mmol) in NMP was degassed with nitrogen for 5 minutes. Xantphos (168 mg, 0.290 mmol) and Pd2dba3 (266 mg, 0.290 mmol) were added and the mixture was heated in a microwave reactor at 160° C. for 10 minutes. The reaction mixture was subsequently diluted with EtOAc. The organic phase was washed with water (2×), dried, and concentrated in vacuo. The crude product was purified by preparative HPLC eluting with a gradient of 45-70% ACN in water (acid mode) to give the title compound as a yellow solid (175 mg, 17.8%).
