A mixture of (S)-1-(6-bromo-5-hydroxy-2-methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.200 g, 0.71 mmol), 1-allyl-2-bromo-1H-benzo[d]imidazole (0.340 g, 1.44 mmol), and potassium carbonate (0.293 g, 2.12 mmol) in N,N-dimethylacetamide (10 mL) was heated in the microwave for 2 h at 200° C. The reaction mixture was cooled to room temperature, filtered, and concentrated under vacuum. The residue was purified via preparative thin layer chromatography (eluting with 20% ethyl acetate/petroleum ether) to afford (S)-5-(1-allyl-1H-benzo[d]imidazol-2-yloxy)-6-bromo-2-methyl-1,2,3,4-tetrahydroquinoline (0.115 g, 41%) of as a light yellow solid. MS (ESI, pos. ion) m/z 398, 400 [M+H]+.
