To a stirred solution of 2-methyl-5-(1-piperazinyl)quinoline (D6, 0.14 g, 1 eq) in dry DMF (5 mL) were added potassium carbonate (0.11 g, 1.2 eq) and a solution of N-[3-(2-chloroacetyl)phenyl]acetamide (J. Chem. Soc., 1949, 552, 553, 0.17 g, 1.2 eq) in DMF (3 mL) under an inert atmosphere. The reaction was stirred for 1.5 hrs. The mixture was diluted with water (8 mL) and extracted with DCM (3×15 mL). The organic phase was washed with brine (25 mL), dried over sodium sulfate and the solvent was removed under reduced pressure. The crude material was purified on SPE cartridge (Silica) using as eluant DCM-methanol (95:5), affording the title compound in 42% yield (0.104 g).
