(1R,3S)-3-[[2-(5-chloro-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]-1-methyl-cyclohexanecarboxylic acid, 826, (0.050 g, 0.108 mmol), benzotriazol-1-yl-[bis(dimethylamino)methylene]oxonium hexafluorophosphate (0.081 g, 0.216 mmol) and N-ethyl-N-isopropyl-propan-2-amine (0.075 mL, 0.432 mmol) were combined in 5 mL of THF. To the reaction was then added ammonia hydrochloride (0.002 g, 0.032 mmol) and the reaction was allowed to stir overnight at room temperature. After concentration under reduced pressure, the mixture was purified by reverse phase HPLC chromatography, yielding 3.3 mg of desired product.
