PROCEDURE

实验过程

To a solution of 4-Iodo-3-(2-methyl-allyloxy)-benzoic acid methyl ester (455 mg, 1.37 mmol) obtained in Example 4(A), in DMF (15 mL) were added Potassium carbonate (379 mg, 2.74 mmol), Tetrabutylammonium chloride (380 mg, 1.37 mmol), Palladium acetate (25.6 mg, 0.136 mmol) in DMF (5 mL) and Phenylboronic acid (200 mg, 1.64 mmol). The resulting mixture was stirred for 3 h at 115° C., cooled to room temperature, filtered over silica, washed with water, dried over MgSO4 and concentrated. Column chromatography (silica gel, heptane/CH2Cl2: 4/6) afforded 368 mg (95%) of the title compound as a slightly brown oil which crystallize. Mp: 52° C.
