Versuchsvorschrift

To a solution of 6-hydroxy-1-tetralone (2.5 g, 15.4 mmol) and 2-iodobenzotrifluoride (25 g, 92 mmol) in DMF (50 mL) was added NaH (0.74 g, 60%, 18.5 mmol) at rt. The mixture was heated to 50° C. until the solid was dissolved and then cooled. To the mixture was added CuCl (1.53 g, 15.4 mmol), followed by tris(dioxa 3,6-heptyl)amine (1.65 mL, 5.15 mmol). The mixture was heated at 145° C. overnight. The reaction was diluted with water, extracted with EtOAc, washed with brine, dried (Na2SO4), and concentrated. Purification by silica gel chromatography (0-20% EtOAc/hexanes) gave 850 mg (18%) of the title compound as a yellow oil. 1H NMR (400 MHz, CDCl3): δ 2.09-2.16 (2H, m), 2.63 (2H, t, J=6.2 Hz), 2.91 (2H, t, J=6.1 Hz), 6.82 (1H, d, J=2.4 Hz), 6.86 (dd, 1H, J=8.6, 2.4 Hz), 7.05 (1H, d, J=8.2 Hz), 7.27 (1H, td, J=8.2, 0.6 Hz), 7.51-7.56 (1H, m), 7.71 (1H, dd, J=7.8, 1.2 Hz), 8.07 (1H, d, J=8.2 Hz). [M+H] calc'd for C17H13F3O2, 307. found 307.
