Reaction Steps

To (Z)-5((7-(cyclopropylamino)-5-(piperazin-1-yl)pyrazolo[1,5-a]pyrimidin-3-yl) methylene) imidazolidine-2,4-dione (step b) (10 mg, 0.027 mmol) in 50.0 uL NMP, was added HOBT (4.4 mg, 0.032 mmol), cyclopropyl acetic acid (60 ul in 0.02M NMP solution), DIPEA (9.5 ul, 0.067 mmol) and EDC (7.8 mg, 0.040 mmol). The reaction mixture was stirred at room temperature for one hour. Diluted the reaction mixture with methanol and prepared by HPLC to yield (Z)-5-((5-(4-(2-cyclopropylacetyl)piperazin-1-yl)-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)imidazolidine-2,4-dione. LCMS (M+1=451)
