Potassium Carbonate → HCID 57824455, compound

Participants

Reaction Steps

4-(2-Chloropyrimidin-5-yl)-benzaldehyde (0.92 mmol), 4-trifluoromethoxyphenyl boronic acid (1.10 mmol), dichlorobis(triphenylphosphine)-palladium(II) (0.01 mmol), 2 M potassium carbonate (0.92 mL) and dioxane (5 mL) were combined in a vial and irradiated by microwave for 10 min at 150° C. The organic layer from the reaction mixture was loaded directly onto silica and dried in vacuo. Purification by silica gel chromatography (EtOAc/hexanes) yielded the product (140 mg) as a white solid: 1H NMR (400 MHz, CDCl3) δ 10.11 (s, 1H), 9.07 (s, 2H), 8.57 (d, J=9.0 Hz, 2H), 8.07 (d, J=8.5 Hz, 2H), 7.82 (d, J=8.3 Hz, 2H), 7.35 (d, J=8.3 Hz, 2H); EIMS m/z 344 (M+).
