Reaction Steps
5-Bromopyridin-3-amine (0.433 g, 2.5 mmol), 4,4,5,5-tetramethyl-2-(prop-1-en-2-yl)-1,3,2-dioxaborolane (0.630 g, 3.75 mmol), Cs2CO3 (3.10 g, 9.5 mmol) and Pd(PPh3)4 (0.289 g, 0.25 mmol) were suspended in DMF/H2O (3:1, 20 mL). The reaction mixture was degassed with N2 and heated at 90° C. for 16 h. Solvent was removed under reduced pressure. The residue was diluted with H2O (20 mL) and extracted with EtOAc (3×50 mL). The combined organic layers were washed with brine (20 mL), dried, concentrated in vacuo and purified by chromatography to afford 5-(prop-1-en-2-yl)pyridin-3-amine (0.773 g, 230%) as a dark yellow oil. MS (ESI) m/z: 135.0 (M+H+).
