Versuchsvorschrift
1,3-Dihydro-isoindole-2,5-dicarboxylic acid 2-benzyl ester 5-methyl ester (2.25 g) is suspended in THF (8 mL) and treated with an aqueous 2N LiOH solution. (5.51 mL) and stirred 14 h at ambient temperature. After evaporation, the residue is partitioned between dichloromethane and water. The organic phase is dried and evaporated. 2.05 g of the title compound are obtained with MP 197-199° C.
