Reaction Steps

1-(Trans-3-aminocyclobutyl)-3,3-dimethyl-1H-pyrrolo[2,3-b]pyridin-2(3H)-one hydrochloride (intermediate 26, 100 mg, 0.329 mmol), 2-chloro-5-ethylpyrimidine (0.047 mL, 0.329 mmol), and potassium carbonate (0.079 mL, 1.315 mmol) were mixed in DMSO (0.7 mL) in a microwave vial. The reaction mixture was stirred at 80° C. for 16 hours. The temperature was increased to 100° C. and the reaction stirred for another 9 hours. The reaction mixture was diluted with water and extracted with ethyl acetate. The organic layer was separated, washed with brine, dried over magnesium sulfate, and concentrated. The resulting crude product was purified via silica gel flash column chromatography eluting with 0 to 100% ethyl acetate in hexanes to yield 1-(trans-3-((5-ethylpyrimidin-2-yl)amino)cyclobutyl)-3,3-dimethyl-1H-pyrrolo[2,3-b]pyridin-2(3H)-one as an off-white solid.
