실험 절차
By using 1-(2,2,4,6,7-pentamethyl-2,3-dihydro-1-benzofuran-5-yl)piperazine hydrochloric acid salt (311 mg, 1.00 mmol) synthesized in Reference example 147 and 4-bromo-1,2-dimethoxybenzene (326 mg, 1.50 mmol), the reaction was carried out in the same manner as Example 23 to synthesize the title compound 131 mg (yield 32%).
