Reaction Steps

tert-Butyl piperazine-1-carboxylate (1.4 g, 7.52 mmol) was added to a mixture of 5-(2-bromoethoxy)-2-methylquinoline (2 g, 7.52 mmol) and potassium carbonate (4.16 g, 30.1 mmol) in N,N-dimethylformamide (20 mL). The reactants were heated at 70° C. for 16 h under an atmosphere of argon. The reaction mixture was poured into water (200 mL) and extracted into ethyl acetate (3×200 mL). The organic layers were combined, dried (Na2SO4) and concentrated in vacuo. The residue was purified by column chromatography, eluting with 30% ethyl acetate in hexane affording the title compound as a tan solid (1.04 g, 37%).
