Procedure

A solution of tert-butyl 4-((2-chloro-5-iodopyridin-4-ylamino)methyl)piperidine-1-carboxylate (Synthesis 170-B) (0.100 g, 0.22 mmol), (E)-2-(3-methoxyprop-1-enyl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.044 g, 0.22 mmol), sodium carbonate (0.5 M, 0.66 mL) and tetrakis(triphenylphosphine) palladium(0) (0.013 g, 0.01 mmol) in acetonitrile (2.00 mL) was heated under microwave irradiation for 20 min at 100° C. The solvent was removed in vacuo and the crude product was purified by silica column chromatography, eluting with ethyl acetate and hexane (1/1). to give the title compound as a colourless oil (0.057 g, 65%).
