Procedure

1-(5-(4-((7R,8aS)-octahydro-5,5-dimethylindolizin-7-ylamino)-5-fluoropyrimidin-2-ylamino)-2-bromo-4-fluorophenyl)-4-methyl-1H-tetrazol-5(4H)-one (301.9 mg, 0.55 mmol) was weighed out and added to a reaction tube with magnetic stir bar. It was dissolved in 24 mL of a solution of dimethoxyethane, ethanol, and water in a ratio of 7:3:2, respectively. Sodium carbonate (174.6 mg, 1.65 mmol) was weighed out, and vinylboronic acid pinacol ester (0.205 mL, 1.21 mmol) was then added. The solution was subjected to vigorous sub-surface nitrogen sparging. Bis(triphenylphosphine)palladium(II) dichloride (17.3 mg, 0.025 mmol) was weighed out and added, the tube was sealed under nitrogen, and the reaction was heated overnight at 110° C. The reaction solution was then combined with a 0.162 mmol pilot reaction run under the same conditions. This was concentrated directly onto silica, and purified by column chromatography. Pure fractions were combined, concentrated, and dried under high vacuum to give 256.0 mg of the title compound (72% total).
