Acetonitrile → (5-(1h-Indazol-4-yl)-7-morpholinothiazolo[4,5-d]pyrimidin-2-yl)(4-(methylsulfonyl)piperazin-1-yl)methanone

Participants

Reaction Steps

(5-Chloro-7-morpholinothiazolo[4,5-d]pyrimidin-2-yl)(4-methylsulfonylpiperazin-1-yl)methanone, 1H-indazol-4-yl-4-boronic acid (2.5 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 140° C. for 10 minutes. Water was added and the solution was filtered. The resulting precipitate was washed with methylene chloride and the organic layer was purified by silica gel chromatography followed by reverse phase silica gel chromatography to give the product 141.
