A mixture of (S)-(6-bromo-5-hydroxy-2-methyl-3,4-dihydroquinolin-1(2H)-yl)(cyclopropyl)methanone (1.20 g, 3.87 mmol), 2H-1,2,3-triazole (0.258 g, 3.74 mmol), copper (I) iodide (0.030 g, 0.16 mmol), (1R,2R)—N1,N2-dimethylcyclohexane-1,2-diamine (0.044 g, 0.31 mmol), and potassium carbonate (1.60 g, 11.61 mmol) in N,N-dimethylformamide (20 mL) stirred for 24 h at 120° C. The reaction mixture was cooled to room temperature and poured into ethyl acetate (100 mL). The mixture was washed with water (3×20 mL), dried over anhydrous sodium sulfate, filtered, and concentrated under vacuum. The residue was purified by column chromatography on silica gel (eluting with 1:3, ethyl acetate/petroleum ether) to afford (S)-cyclopropyl(5-hydroxy-2-methyl-6-(2H-1,2,3-triazol-2-yl)-3,4-dihydroquinolin-1(2H)-yl)methanone (0.150 g, 13%) as light yellow oil. MS (ESI, pos. ion) m/z 299 [M+H]+.
