A solution of 2-(4-((4-((2,4,6-trifluorobenzyl)amino)pyrimidin-2-yl)amino)-1H-pyrazol-1-yl)acetic acid I-2 (0.1 g, 0.26 mmol, prepared by Procedure B), DIPEA (0.15 mL, 0.8 mmol), 2-aminopropanenitrile hydrochloride (34 mg, 0.3 mmol), propylphosphonic anhydride solution (50% in DMF) (0.17 g, 0.5 mmol) in DMF was stirred overnight at room temperature then extracted into water and washed with DCM. The aqueous layer was neutralised with aqueous sodium bicarbonate and extracted with three times with DCM. The combined organic layer was concentrated in vacuo and purified by prep. HPLC to afford N-(1-cyanoethyl)-2-(4-((4-((2,4,6-trifluorobenzyl)amino)pyrimidin-2-yl)amino)-1H-pyrazol-1-yl)acetamide I-5 (80 mg, 0.18 mmol). LC-MS (Method B), RT=5.15 min. (ES+) 431.
