Reaction Steps
2-Bromo-6-fluoro-4-methylpyridine (380 mg, 2 mmol), tert-butyl piperazine-1-carboxylate (466 mg, 2.5 mmol), Pd2(DBA)3 (40 mg, 0.044 mmol), sodium tert-butoxide (317 mg, 3.3 mmol) and BINAP (80 mg, 0.032 mmol) were dissolved in anhydrous THF (6 ml) under argon and heated at 80° C. under microwave heating. The mixture was diluted with ethyl acetate, filtered, the filtrate was evaporated under reduced pressure. The residue was dissolved in DCM and filtered through a pad of silica. The silica was washed with a mixture of DCM and diethylether, the combined filtrates were concentrated under reduced pressure to yield 360 mg (1.22 mmol, yield 61%) MS (multi-mode) m/z=296.2 [M+1]+.
