Versuchsvorschrift
12 parts of para-[β-(2,3-dihydro-3-hydroxy-3-phenyl-(1H)-isoindol-1-on-2-yl)ethyl]benzenesulphonamide are refluxed for 7 hours with 120 parts of 98% formic acid. After concentration in vacuo, the residue is recrystallized in 110 parts of ethyl acetate to give 8 parts of the desired product, m.p.: 218° C.
