실험 절차

Tripotassium phosphate (28.1 g, 132 mmol) was added to a solution of toluene (200 mL) containing 2,2,7-trimethyl-2,3-dihydro-1-benzofuran (10.0 g, 5.08 mmol) synthesized in Reference Example 155, bis(triphenylphosphine)nickel (II) dichloride (0.998 g, 1.53 mmol), triphenylphosphine (0.800 g, 3.05 mmol) and 4-methylphenyl borate (8.99 g, 66.1 mmol), and the mixture was stirred under heated reflux for 2 hours. After cooled to room temperature, the reaction solution was filtered using Celite. Water was added to the obtained filtrate, and it was subjected to extraction using ethyl acetate. The extract was dried using anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. After that, the obtained residue was purified by silica gel column chromatography (hexane-ethyl acetate 20:1) to give 12.1 g of the title compound as a brown solid (yield: 94%).
