실험 절차

To a solution of 5 parts of cis-1,2-cyclohexane dicarboxylic anhydride in 75 parts of glacial acetic acid was added 4.8 parts of 4-amino-3-fluorobenzonitrile in one portion. The mixture was refluxed for 4 hours, poured over 200 parts of ice and filtered. The crude crystalline product was recrystallized from methanol to yield 4.4 parts of beige 4-(1,3-dioxo-2,3,3a,4,5,6,7,7a-octahydro-1H-isoindol-2-yl)-3-fluorobenzonitrile melting 120°-123°.
