実験手順

To (Z)-5-((5-(5-chloro-2-fluorophenylamino)-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)-3-(hydroxymethyl)imidazolidine-2,4-dione (100 mg, 0.218 mmol) in DMF (3 mL) was added 3-(4-methylpiperazin-1-yl)propanoic acid (75 mg, 0.436 mmol), dicyclohexylcarbodiimide (90 mg, 0.436 mmol), and DMAP (4.0 mg, 0.33 mmol). The reaction mixture was stirred at room temperature overnight and then diluted with ethyl acetate and washed 1× water, 3× brine. The organic layer was dried with MgSO4, filtered and adsorbed onto silica gel. The crude material was purified by column chromatography eluting with 0-10% MeOH/CH2Cl2 gradient. Pure fractions were combined and the solvent was removed. This material was crystallized from ethyl acetate and hexane to provide 35 mg (26%) of (Z)-(4-((5-(5-chloro-2-fluorophenylamino)-7-(cyclopropylamino)pyrazolo[1,5-a]pyrimidin-3-yl)methylene)-2,5-dioxoimidazolidin-1-yl)methyl 3-(4-methylpiperazin-1-yl)propanoate as a yellow solid. LCMS (ES): >95% pure, m/z 612 [M+1]+.
