Reaction Steps

To a 10 mL vial were added tert-butyl (S)-4-(5-(1-((5-cyano-6-ethyl-2-(methylsulfonyl)pyrimidin-4-yl)amino)ethyl)-1-methyl-1H-pyrrolo[3,2-b]pyridin-6-yl)piperazine-1-carboxylate (32 mg, 0.056 mmol) in dioxane (2 mL) along with 0.5 M ammonia in dioxane (6.09 μL, 0.281 mmol) to give a yellow solution. The vial was sealed and the reaction mixture was stirred overnight at 75° C. The next day LCMS indicated the reaction was incomplete. Additional NH3 solution (2 eq) was added and the reaction mixture was allowed to stir for 6 hours at 75° C. LCMS showed the reaction was mostly complete. The reaction mixture was diluted with EtOAc and washed with saturated aqueous NH4Cl (3×). The combined organic layers were dried over MgSO4, filtered, and concentrated. The product was purified by column chromatography (ISCO 4 g, 50-100% EtOAc/hexane gradient) to give the title compound as a yellow oil.
