PROCEDURE

实验过程

Pd2(dba)3-CHCl3 (5 mg, 0.5 mol %), ligand 1 (8 mg, 2 mol %) and 1.4 eq sodium tert-butoxide (13 mg, 0.14 mmol) were weighed in air and transferred into a microwave tube, followed by dioxane (750 μL), 1.0 eq N,N-dimethyl-1-(piperidin-4-yl)-2′H-spiro[piperidine-4,4′-quinoline]-1′(3′H)-carboxamide (36 mg, 0.10 mmol) and 1.0 eq 5-chloro-2,3-dimethylpyrazine (14 mg). The tube was flushed with nitrogen, capped and stirred at 80° C. for 3 hours. The reaction was cooled to room temperature, diluted with methanol (500 μL), filtered (Whatman 0.45 μm PTFE) and subjected to reverse-phase HPLC purification (2-40% CH3CN gradient [w/0.1% TFA (aq)] over t=10 minutes, 750 μL injected, 35 mL/min) to yield compound no. 20. LC/MS (10-99% CH3CN/0.05% TFA gradient over 5 min): m/z 463.4, retention time 2.13 minutes.
