A 40-mL resealable tube was charged with 1-[(2S)-6-bromo-5-hydroxy-2-methyl-1,2,3,4-tetrahydroquinolin-1-yl]ethan-1-one (90 mg, 0.32 mmol), 2,2-dichloroethyl methanesulfonate (82 mg, 0.42 mmol), potassium carbonate (135 mg, 0.96 mmol), and N,N-dimethylformamide (10 mL). The resulting mixture stirred for 48 h at 110° C. After cooling to room temperature, the reaction mixture was filtered and concentrated under reduced pressure. The residue was purified by preparative thin layer chromatography (eluting with petroleum ether/ethyl acetate, 10:1 then 1:2) to afford 1-[(2S)-6-bromo-5-(2,2-dichloro ethoxy)-2-methyl-1,2,3,4-tetrahydroquinolin-1-yl]ethan-1-one (56 mg, 46%) as light yellow oil. MS (ESI, pos. ion) m/z 31, 383 [M+H]+.
