Reaction Steps
The general procedure from Example 12 was followed using 4-chloroanisole (143 mg, 1.0 mmol) and 4—MeOC6H4B(OH)2 (228 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 3.0 mL of 1,4-dioxane. After 24 h, the reaction mixture was chromatographed with 5% ethyl acetate/hexane to give 213 mg (99% yield) of 4-(4-methoxyphenyl)anisole. It was >95% pure by 1H NMR and GC/MS. 1H NMR (500 MHz, CDCl3): δ7.38 (d, J=8.68 Hz, 4H), 6.86 (d, J=8.68 Hz, 4H), 3.74 (s, 6H) ppm. 13C NMR (125 MHz, CDCl3): δ158.7, 133.5, 127.7, 114.2, 55.3 ppm.
