Reaction Steps

To a solution of 5-chloro-N2-(1,5-dimethyl-1H-pyrazol-3-yl)-N4-(octahydro cyclopenta[c]pyrrol-5-yl)pyrimidine-2,4-diamine (522.0 mg, 1.50 mmol) and 2-cyanoacetic acid (127.6 mg, 1.50 mmol) in a mixture of DCM (40 mL) and DMF (10 mL) were added HATU (690.2 mg, 1.82 mmol) and Et3N (313.5 mg, 3.10 mmol). After addition, the reaction mixture was stirred at rt for 1.5 h, then quenched with H2O (30 mL) and extracted with DCM (100 mL×3). The combined organic phases were washed with brine (100 mL), dried over anhydrous Na2SO4, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (DCM/MeOH (v/v)=80/1) to give the title compound as a beige solid (455.2 mg, 73.1%).
