Procedure

A solution of 17.0 g (50 mmol) of 2-[4-(3-nitro-phenoxy)-butyl]-isoindole-1,3-dione in 1000 ml of ethanol is mixed with 25 ml of hydrazine and stirred for 2 hours at 70° C. After cooling, the precipitate that is formed is suctioned off, and the filtrate is spun in. The residue is taken up in dichloromethane. It is filtered again, and the filtrate is fully concentrated by evaporation. 5.8 g (28 mmol, corresponding to 56% of theory) of the product is obtained.
