Reaktionsschritte

1.20 g (4.46 mmol) of 2-benzyl-5,6-dimethoxyisoindoline was dissolved in 40 ml of methanol at 40° C., and 84 mg of 10% palladium carbon was added thereto. Under a hydrogen stream, catalytic reduction was conducted at the same temperature for 4 hours. The solvent was distilled off under reduced pressure, and a small amount of ethyl acetate and diethylether was added to the residue and stirred. The precipitates were collected to obtain 617 mg (yield: 77.3%) of the above identified compound.
