Reaction Steps

To a solution of 5-chloro-N2-(5-cyclopropyl-1H-pyrazol-3-yl)-N4-(octahydrocyclopenta[c]pyrrol-5-yl)pyrimidine-2,4-diamine (153.3 mg, 0.43 mmol) in DCM (10 mL) were added Et3N (82.3 mg, 0.81 mmol) and acetyl acetate (62.5 mg, 0.61 mmol). The reaction mixture was stirred at rt for 15 min, then quenched with H2O (30 mL) and extracted with DCM (100 mL×3). The combined organic phases were washed with brine (100 mL), then dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (MeOH/DCM (v/v)=1/50) to give the title compound as a beige solid (79.0 mg, 46.1%).
