YieldReaction ConditionsOperation in experiment
74% General procedure: Boronic acid 19 (1.5 equiv.) in dry toluene (8 mL) reacted at room temperature for 10 min with K3PO4 ( 2.0 equiv.), PPh3 (0.02 equiv.) and Pd(OAc)2 (0.01 equiv.), under argon atmosphere. Bromine derivative 18 ( 1.0 equiv.) were added and the reaction was heated at 100 C for 16 h. A solution of NaOH (1M) was added and the crude product was extracted with diethyl ether (3x 20 mL). Final compounds were obtained by column chromatography over silica gel.Elution with Petroleum Ether/EtOAc 90:10, afforded compound 20 as sheer oil (0.202g, 74%). H1-NMR (CDCl3, 300 MHz) δ 3.92 (s, 6H), 4.10 (s,; 3H); 4.2 (s; 2H); 6.5 (dd; 1H; J= 6.68-1.7 Hz ); 6.7 (s; 1H); 7.10 (d; 1H; J= 7.02 Hz); 7.5 (d; 1H, J= 8.55 Hz); 7.7 (s; 1H); 7.8 (d; 1H; J= 8.33 Hz); 7.9 (d; 1H; J= 7.23 Hz); 8.1 (d; 1H; J= 8.11 Hz ); 8.6 (s; 1H).
