Participants

Reaction Steps

To a solution of 3-(4-isopropylphenyl)-4,6-dimethyl-2,3-dihydro-1-benzofuran synthesized in Reference Example 15 (5.62 g, 21.1 mmol) in acetonitrile (60 mL) was added N-bromosuccinimide (3.76 g, 21.1 mmol) at 0° C., and the mixture was stirred at the same temperature for 1 hour. The solvent was distilled off under reduced pressure to obtain a residue, which was purified by silica gel column chromatography (hexane:ethyl acetate=10:1) to obtain 5.95 g (yield 82%) of the title compound. Melting point: 90-91° C. (methanol).
