Procedure

Two capped 0.5 mL microwave reaction vials each containing a solution of tert-butyl 4-((2-amino-5-bromopyridin-4-ylamino)methyl)piperidine-1-carboxylate (30 mg, 0.078 mmol), 4-methoxyphenyl boronic acid (17.8 mg, 1.5 eq.), Pd(PPh3)4 (4.5 mg, 5 mol %), 0.5M aqueous sodium carbonate (0.23 mL, 1.5 eq.) in acetonitrile (0.78 mL) were heated at 150° C. for 20 min by microwave irradiation. After cooling, the contents of the two reaction vials were combined and solvents were removed in vacuo. The crude product was purified by chromatography using a Biotage SNAP silica (10 g) column, eluting with a gradient of methanol/NH3 (99/1) in dichloromethane, to give the title compound as a yellow solid (48 mg, 75%).
