The general procedure from Example 12 was followed using 2-chloro-anisole (143 mg, 1.0 mmol) and 4—MeC6H4B(OH)2 (204 mg, 1.5 mmol) with Pd2(dba)3 (13.3 mg, 0.0145 mmol) and (Me3C)2PH(O) from Experiment 2 (9.6 mg, 0.058 mmol) and CsF (456 mg, 3.0 mmol) in 4.0 mL of 1,4-dioxane. After 24 h, the reaction mixture was chromatographed with 5% ethyl acetate/hexane to give 165 mg (83% yield) of 2-(4-methylphenyl)anisole. It was >95% pure by 1H NMR and GC/MS. 1H NMR (500 MHz, CDCl3): δ7.32 (d, J=8.06 Hz, 2H), 7.18 (m, 2H), 7.10 (d, J=7.88 Hz, 2H), 6.92−6.84 (m, 2H), 3.67 (s, 3H), 2.28 (s, 3H) ppm. 13C NMR (125 MHz, CDCl3): δ156.5, 136.5, 135.6, 130.7, 129.4, 128.7, 128.3, 120.8, 111.2, 55.5, 21.1 ppm.
