Reaktionsschritte
A mixture 2,6-Dimethyl-4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenol (500 mg, 2.02 mmol, 1 eq.), 1-bromopropane (793 mg, 6.45 mmol, 3.2 eq.), and K2CO3 (334 mg, 2.42 mmol, 1.2 eq.) in acetone (20 mL) is heated at 65° C. for 4 days. After cooling to room temperature, the reaction is concentrated, diluted with EtOAc and sequentially washed with H2O and saturated aqueous NaCl. The organic solution is dried over Na2SO4 and concentrated to give 2-(3,5-Dimethyl-4-propoxy-phenyl)-4,4,5,5-tetramethyl-[1,3,2]dioxaborolane as a clear oil.
