반응 단계

N,N-Diisopropylethylamine (0.8 mL; 5 eq) was added to a solution of 2-methyl-5-(1-piperazinyl)quinoline (D3) (0.2 g; 1 eq) and 2-(3-nitrophenyl)ethyl methanesulfonate (D4) (0.22; 1 eq) in dimethylformamide (1.5 mL). The reaction mixture was heated to 100° C. for 10 hours. The dark solution was concentrated under reduced pressure, diluted with water (3 mL) and brine (1 mL) and extracted into ethyl acetate (3×3 mL). The organic layers were combined, dried over Na2SO4 and concentrated under reduced pressure. The crude was purified by flash chromatography, eluting with a gradient from dichloromethane to dichloromethane/MeOH (98/2) affording the title compound in 64% yield (0.21 g).
