Reaction Steps
To a mixture of 3-methyl-1-benzothiophene (5.00 g), isovaleryl chloride (4.52 mL) and nitromethane (50 mL) was added aluminum (III) chloride (8.98 g) at 0° C., and the mixture was stirred at 0° C. for 30 min then at room temperature for 4 hr. The reaction mixture was poured into ice-cooled water, and the mixture was extracted with ethyl acetate. The extract was washed with 1N hydrochloric acid and saturated brine, dried over magnesium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate:hexane=1:19, volume ratio) to give the title object compound (7.72 g, 99%) as a yellow oil.
