1.0 g (3.1 mmol) of N-benzyl-5,6-dihydroxyisoindoline hydrobromide was dissolved in 40 ml of a 50% methanol aqueous solution, and the solution was adjusted to pH 8.0 with 8% aqueous ammonia. The precipitated crystals were collected by filtration and washed with 5 ml of cold water and 5 ml of cold acetone to obtain 640 mg of the above identified compound.
