Reaction Steps

To a solution of 2,6-dichloro-4-(3-pyridyl)pyridine (48 mg, 0.21327 mmol) and 3,3-difluoropyrrolidine hydrochloride (153 mg, 5.0 equiv., 1.0663 mmol) in NMP (1.0 mL, 10 mmol) in a microwave vial was added DIPEA (0.26 mL, 7.0 equiv., 1.4929 mmol), and the reaction was maintained at 140° C. for 60 min then at 150° C. for 20 min in the microwave machine, while LCMS indicated the conversion was more than 95%. The crude was used without further treatment. LCMS: m/z 296 (M+H).
