Reaktionsschritte

1-Bromo-3-[2-(tert-butyldimethylsilyloxy)ethyl]benzene (2.5 g, 7.96 mmol), N-methylaniline (1.02 g, 9.55 mmol), Pd2dba3 (364 mg, 0.4 mmol), Xantphos (691 mg, 1.19 mmol) and NaOtBu (727 mg, 9.55 mmol) were combined in toluene (12 mL), and the reaction was heated at 100° C. in the microwave for 90 min. The reaction was diluted with EtOAc, washed with brine, dried (MgSO4), and concentrated. The residue was stirred in 70% TFA/DCM (10 mL) for 2 h. The solution was concentrated and purified by silica gel chromatography (30% to 100% EtOAc/hexanes) to give 1.3 g (72%) of the title compound as a clear oil. 1H NMR (400 MHz, CDCl3): δ 1.53 (1H, br s), 2.81 (2H, t, J=6.5 Hz), 3.31 (3H, s), 3.83 (2H, t, J=6.5 Hz), 6.81 (1H, d, J=7.4 Hz), 6.86-6.89 (2H, m), 6.97 (1H, t, J=7.3 Hz), 7.04 (d, 2H, J=7.8 Hz), 7.18-7.29 (3H, m). [M+H] Calc'd for C15H17NO, 228. Found, 228.
