Reaction Steps

To a solution of 1-(4-chloro-2,6-dimethylphenyl)ethanone (5.0 g, 27.4 mmol), K3PO4 (11.6 g, 54.7 mmol), sesamol (4.54 g, 32.9 mmol) in toluene (54.8 mL), was added 2-di-tert-butylphosphino-2′,4′,6′-triisopropylbiphenyl (349 mg, 0.82 mmol), Pd(OAc)2 (259 mg, 1.15 mmol). The reaction was heated at 100° C. overnight under N2. The solution was cooled to room temperature and filtered through a small pad of diatomaceous earth. The cake was washed with ethyl acetate (50 mL) and combined filtrate was concentrated under reduced pressure. The residue was recrystallized in MeOH to give 1-(4-(benzo(d)(1,3)dioxol-5-yloxy)-2,6-dimethylphenyl)ethanone (4.80 g) as white solids in 62% yield: 1H NMR (500 MHz, CDCl3) δ 6.77 (d, J=8.5 Hz, 1H), 6.59 (s, 2 H), 6.56 (s, 1 H), 6.48 (m, 1 H), 5.98 (s, 2 H), 2.46 (s, 3 H), 2.21 (s, 6 H).
