Reaction Steps

To a vial containing 9-bromo-10-fluoro-2,5-diazatetracyclo[11.1.1.0[2,6].0[7,12]]pentadeca-3,5,7,9,11-pentaene-4-carboxamide (0.1 g), palladium acetate (0.05 eq), sodium acetate (4 eq) and tetrabutylammonium chloride (1 eq) was added DMF (15 mL/mmol) and 1-fluoro-2-methyl-4-triethylsilyl-but-3-yn-2-ol (2 eq) dropwise. The reaction was sealed and heated to 100° C. for 15 minutes in a biotage microwave. The reaction mixture was extracted with DCM and saturated ammonium chloride. The organic layer was dried with magnesium sulfate, filtered, concentrated to dryness and purified by reverse phase hplc to afford (±) 10-fluoro-9-(4-fluoro-3-hydroxy-3-methylbut-1-yn-1-yl)-2,5-diazatetracyclo[11.1.1.0[2,6].0[7,12]]pentadeca-3,5,7(12),8,10-pentaene-4-carboxamide.
