Reaction Steps

To a solution of methyl magnesium bromide (THF solution 3.0 M, 1.0 mL, 3.0 mmol) in THF (5 ml) at −30° C. was added 5-(4-(4-methoxyphenyl)piperazin-1-yl)-2,2,4,6-tetramethyl-3-(4-methylphenyl)-2,3-dihydro-1-benzofuran-7-carbaldehyde (310 mg, 640 mmol) obtained in Example 105. The reaction mixture was stirred for 20 minutes under the same temperature. The resulting mixture was poured into water and extracted with ethyl acetate. The organic extract was washed with water and saturated aqueous sodium chloride, dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was crystallized from hexane-ethyl acetate to obtain 19.5 mg (yield 61%) of the title compound. mp. 149–151° C.
