Versuchsvorschrift

A 100-mL, round-bottom flask equipped with a balloon filled with air was charged with (S)-1-(6-bromo-5-hydroxy-2-methyl-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.300 g, 1.06 mmol), 4-carbamoylphenylboronic acid (0.437 g, 2.65 mmol), pyridine (1 mL), dichloromethane (40 mL), copper (II) acetate (0.580 g, 3.20 mmol) and 4 Å molecular sieves (4.0 g). The resulting mixture stirred for 3 days at room temperature. The reaction mixture was filtered, and the filtrate was concentrated under vacuum. The residue was purified by preparative thin layer chromatography (eluting with 3:1, ethyl acetate/petroleum ether) to afford (S)-4-(1-acetyl-6-bromo-2-methyl-1,2,3,4-tetrahydroquinolin-5-yloxy)benzamide (0.148 g, 35%) as yellow oil. MS (ESI, pos. ion) m/z 403, 405 [M+H]+.
