実験手順

To a 40 mL scintillation vial was charged 5-chloro-3-(quinolin-3-yl)-N,N-bis((2-(trimethylsilyl)-ethoxy)methyl)pyrazolo[1,5-a]pyrimidin-7-amine (0.86 mmol, 480 mg), tert-butyl 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-5,6-dihydropyridine-1(2H)-carboxylate (1.30 mmol, 400 mg), K3PO4 (2.60 mmol, 550 mg), and PdCl2(dppf).CH2Cl2 (0.086 mmol, 70 mg). To this reaction mixture was added a 9:1 solution of 1,4-dioxane:H2O (10 mL). The vial was flushed with argon, sealed with Teflon tape, and stirred at 100° C. 18 hours. After 18 hours, the reaction was concentrated in vacuo and the residue purified via silica gel chromatography to yield tert-butyl 4-(7-(bis((2-(trimethylsilyl)ethoxy)methyl)amino)-3-(quinolin-3-yl)pyrazolo[1,5-a]pyrimidin-5-yl)-5,6-dihydropyridine-1(2H)-carboxylate (586 mg, 833 mmol, 97% yield) as yellow solid.
