実験手順

To a solution of 6-bromo-2-chloroquinoline of Step A (1.25 g, 5.15 mmol) in N,N-dimethylformamide (35 mL) is added piperazine (4.43 g, 51.4 mmol) and the mixture is heated at 110° C. under nitrogen for 3 hours. After cooling, it is diluted with saturated aqueous sodium bicarbonate and extracted with ethyl acetate. The extracts are dried over anhydrous magnesium sulfate and evaporated to dryness.
