Procedure

A solution of tert-butyl 4-((2-chloro-5-iodopyridin-4-ylamino)methyl)piperidine-1-carboxylate (0.100 g, 0.22 mmol), sodium carbonate (0.5 M, 0.66 mL), phenyl boronic acid (0.027 g, 0.221 mmol) and tetrakis(triphenylphosphine) palladium(0) (0.011 g, 0.01 mmol) in acetonitrile (2 mL) was heated at 100° C. for 20 min under microwave irradiation. The reaction mixture was concentrated in vacuo. The crude product was purified by chromatography on a short silica column, eluting with ethyl acetate/petroleum ether (3/7), to give the title compound as a colourless oil (0.088 g, 98%).
