반응 단계
A mixture of 2-amino-5-bromopyridine 10-1 (10 g, 58 mmol), tert-butyl acrylate (50 mL, 344 mmol), triethylamine (50 mL, 359 mmol), tri-o-tolylphosphine (3.0 g, 9.8 mmol) and Pd(OAc)2 (1.0 g, 4.5 mmol) in 150 mL CH3CN was purged with argon for 5 min and subsequently refluxed at 110° C. for 20 hr. The mixture was then cooled and concentrated. The residue was purified using silica gel flash chromatography (EtOAc/hexanes 1:1) to afford the desired product 10-2 as a solid.
