Reaction Steps

To a solution of tert-butyl 2-(aminomethyl)-4,4-difluoro-piperidine-1-carboxylate, 13i, (0.10 g, 0.41 mmol) and 5-chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine (0.18 g, 0.38 mmol) in THF (2 mL) was added iPr2NEt (0.20 mL, 1.15 mmol). The reaction mixture was heated in microwave at 130° C. for 15 minutes. The reaction was cooled to room temperature and the volatiles were removed under reduced pressure. The crude residue was purified via silica gel chromatography (0-100% EtOAc/hexanes) to afford the desired product, 13j.
