To a solution of 1-cyano-1-cyclopropane-carboxylic acid (0.058 g, 0.527 mmol) in THF at room temperature was added HATU (0.200 g, 0.527 mmol) followed by N,N-diisopropylethylamine (0.334 mL, 1.91 mmol). The solution was stirred for 10 minutes. (1S,3R)—N1-(2-fluoro-5-(5-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)phenyl)cyclohexane-1,3-diamine, 44e, (0.200 g, 0.584 mmol) was then added and solution stirred at room temperature for 4 hours. The mixture was concentrated in vacuo and purified via silica gel chromatography (30-60% Ethyl Acetate/hexanes) to give 80 mg of 871 as off-white solid.
