Reaction Steps

A mixture of 6-bromo-N-(((2R,6S)-2,6-dimethyltetrahydro-2H-pyran-4-yl)methyl)pyridin-2-amine (110 mg, 0.36 mmol), 5-chloro-2-fluoro-pyridine-4-boronic acid (193 mg, 1.10 mmol), 0.55 ml 2.0M saturated sodium carbonate aqueous solution in 2 ml DME was purged with Argon for 3 min, PdCl2(dppf)CH2Cl2 (30 mg, 0.037 mmol) was added to this purged. The resulting mixture was heated at about 95° C. in an oil bath for 3.5 hours. Formation of the desired product was confirmed by LCMS: MH+350, 0.70 min. The preceding reaction mixture was diluted with ethyl acetate, washed with water, brine, dried over sodium sulfate and concentrated. The resulting residue was purified by ISCO eluting with 10% ethyl acetate in heptane to give 90 mg desired product as colorless oil. LCMS (m/z): 350 (MH+), retention time=0.70 min.
