Reaction Steps

Piperidine (323 mg, 3.80 mmol) and potassium carbonate (525 mg, 3.80 mmol) were added to a solution of DMA (3 mL) containing 5-bromo-2-(iodomethyl)-2,4,6,7-tetramethyl-2,3-dihydro-1-benzofuran (300 mg, 0.759 mmol) synthesized in Reference Example 133, and the mixture was stirred under microwave irradiation at 150° C. for 10 minutes. The reaction solution was cooled to room temperature, and water and ethyl acetate were added thereto to separate an organic layer. The organic layer was washed with water and saturated saline, and dried using anhydrous magnesium sulfate, followed by concentration under reduced pressure. The residue was purified by silica gel chromatography (hexane-ethyl acetate 95:5-85:15) to give 170 mg of the title compound (yield: 64%).
