Procedure
By using (5-bromo-2,4,6,7-tetramethyl-2,3-dihydro-1-benzofuran-2-yl)methanol (330 mg, 1.16 mmol) synthesized in Reference example 123 and 1-(4-isopropylphenyl)piperazine (774 mg, 3.78 mmol), the reaction was carried out in the same manner as Example 1 to obtain the title compound 30 mg (yield 6%). Melting point was 160 to 163° C. (ethyl acetate-hexane).
