반응 단계
(+)-5,6-Dimethoxy-2-[2,2,4,6,7-pentamethyl-3-(4-methylphenyl)-2,3-dihydro-1-benzofuran-5-yl]isoindoline (150 mg, 0.327 mmol) was dissolved into a 25% solution of hydrogen bromide in acetic acid and the mixture was concentrated under reduced pressure. The residue was crystallized from methanol to obtain 92 mg (52% yield) of the title compound. Melting point: 174-177° C. [α]D=+40.2° (c=0.495, methanol)
