By using 1-(7-methoxy-2,2,4,6-tetramethyl-2,3-dihydro-1-benzofuran-5-yl)piperazine (436 mg, 1.50 mmol) synthesized in Reference Example 96 and 5-bromo-2,2-difluoro-1,3-benzodioxole (614 mg, 2.25 mmol), the reaction was carried out in the same manner as Reference Example 59 to synthesize 321 mg of the title compound (yield 48%). Melting point was 149 to 151° C. (hexane).
