N,N-Diisopropylethylamine (0.23 mL) was added to a solution of 2-methyl-5-(1-piperazinyl)quinoline (D3) (0.05 g) and 2-[3-(2-oxo-1-pyrrolidinyl)phenyl]ethyl methanesulfonate (0.071 g) in dimethylformamide (1 mL) and the resulting mixture was heated to 100° C. for 18 hours, then cooled to room temperature. The reaction mixture was diluted with ethyl acetate (50 mL) and washed with water (50 mL), a mixture of water and brine (1:1, 2×50 mL) and brine (50 mL). The organic layer was dried over sodium sulfate and concentrated under reduced pressure. The crude was purified by flash chromatography on silica gel, eluting with methanol-ethyl acetate (90:10) affording the title compound in 77% yield (0.07 g).
