실험 절차

To a solution of [(2R)-8-methyl-2,3-dihydro[1,4]dioxino[2,3-f]quinolin-2-yl]methyl 4 bromobenzene sulfonate (2.31 g, 5.13 mmol) in dimethylsulfoxide (123 mL) is added the 6-bromo-2-piperazin-1-yl-quinoline of Step B (1.5 g, 5.13 mmol) and the mixture is heated at 75° C. under nitrogen overnight. The mixture is poured into saturated aqueous sodium bicarbonate and extracted with ethyl acetate. The extracts are dried over anhydrous magnesium sulfate and evaporated to dryness. The residue is flash chromatographed on silica gel Merck-60 using a gradient of methanol (0.5–2%) in ethyl acetate-hexane (55:45) to provide the title compound as an off-white solid (1.02 g), m.p. 153–154° C.
