To 8-(tert-butyldimethylsilyloxy)-2-(7-iodo-[1,2,4]triazolo[4,3-a]pyridin-3-yl)quinoline (2.011 g, 4.003 mmol) in NMP/THF (10 mL/10 mL) was added tributyl(vinyl)stannane (1.523 g, 4.803 mmol), trifuran-2-ylphosphine (0.0929 g, 0.400 mmol), Pd2 dba3 (0.367 g, 0.4003 mmol) and triethylamine (0.405 g, 4.00 mmol). The reaction was degassed with N2 and heated to 60° C. for 1 hour. The crude mixture was diluted with ethyl acetate and the organic layer was washed with H2O. The combined organics fractions were dried over Na2SO4 and concentrated in vacuo. The crude material was purified by flash column chromatography (eluting with a 5:1 mixture of Hexanes/ethyl acetate), affording the desired product.
