Procedure

(4-Hydroxy-2-methyl-phenoxy)-acetic acid methyl ester (215 mg; 1.1 mmol), 3-Bromo-5-isobutoxy-phenylboronic acid (523.4; 1.9 mmol), copper(II) acetate (199 mg; 1.1 mmol), crushed molsieves (about 1 g) and triethylamine (0.46 ml; 3.3 mmol) was dissolved in dichloromethane (40 ml) and stirred over night. The reaction mixture was filtered through celite and evaporated to dryness. The crude product was purified by preparative HPLC (method B). Yield: 300 mg; 65%. HPLC-MS: m/z: 423.5 (M+); Rt: 2.71 min
