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 (54.3 mg, 0.10 mmol) was added to a tared reaction vial with magnetic stir bar and weighed. This was dissolved in 2 mL dimethylformamide and copper(I) cyanide (18.0 mg, 0.20 mmol) was weighed out and added. The reaction was heated at 100° C. for three hours, recharged with additional copper cyanide (37.7 mg, 0.42 mmol) and heated overnight at 115° C. The reaction was diluted into ethyl acetate and washed in succession with brine and water to remove DMF. The ethyl acetate layer was dried over sodium sulfate, filtered, and concentrated onto silica. Product was purified by column chromatography. After drying, 21.1 mg was obtained of the title compound (43% yield).
