5-Chloro-2-iodo-7-morpholinothiazolo[4,5-d]pyrimidine, 3-(methylsulfonyl)phenyl boronic acid and trans-dichlorobis(triphenylphosphine)palladium(II) (0.1 eq) were slurried with equal parts 1M sodium carbonate (3 eq) and acetonitrile. The solution was microwaved at 90° C. for 10 minutes. Water was added and the solution was filtered. The aqueous layer was dried and combined with 5-pyrimidine-2-amine boronic acid (1.2 eq), and trans-dichlorobis(triphenylphosphine)palladium(II) (0.1 eq) were slurried with equal parts 1M sodium carbonate aqueous solution (3 eq) and acetonitrile. The solution was microwaved at 150° C. for 10 minutes. Water was added and the solution was filtered. The resulting precipitate was purified by reverse phase silica gel chromatography to yield 142.
