실험 절차

A mixture of 101a (2.3 g, 10 mmol), 5-(4-methylpiperazin-1-yl)pyridin-2-amine (1.9 g, 10 mmol), XantPhos (576 mg, 1.0 mmol), Pd2(dba)3 (915 mg, 1.0 mmol) and Cs2CO3 (6.5 g, 20 mmol) in dioxane (50 mL) was heated at 100° C. for 12 h under nitrogen. It was then filtered and evaporated in vacuo. The residue was purified by silica-gel column eluting with 1:1 ethyl acetate/petroleum ether to afford 101b as a green solid (1.5 g, 44%). MS: (M+H)+ 343.
