Reaction Steps

To 5-((5-chloro-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)thiazolidine-2,4-dione (20 mg, 0.06 mmol) in NMP was added 3-chloroaniline (38 μL, 0.36 mmol) and a few granules of p-toluenesulfonic acid. The reaction was heated in microwave at 180° C. 1.5 hours. The reaction mixture was filtered and purified by prep HPLC then prep TLC (1% MeOH/DCM) to yield 5-((5-(3-chlorophenylamino)-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)thiazolidine-2,4-dione as a yellow solid. LCMS (M+1=427)
