A mixture of 2-(4-((4-((2,4,6-trifluorobenzyl)amino)pyrimidin-2-yl)amino)-1H-pyrazol-1-yl)acetic acid I-2 (80 mg, 0.21 mmol, prepared by Procedure B), DIPEA (187 μL, 1.06 mmol) and TFFH (61 mg, 0.23 mmol) in dioxane (4 mL) was stirred for 10 min at room temperature. Ethylamine (2M in THF, 529 μL, 1.06 mmol) was added and the reaction was stirred for 2 h, then diluted with water and extracted with DCM. The organic layer was concentrated in vacuo and purified by prep. HPLC to afford N-ethyl-2-(4-((4-((2,4,6-trifluorobenzyl)amino)pyrimidin-2-yl)amino)-1H-pyrazol-1-yl)acetamide I-6 (8.8 mg, 0.02 mmol). LC-MS (Method B), RT=5.23 min. (ES+) 406.
