Versuchsvorschrift
Nitration of the 1,3-dihydro-iso-benzofuran derivatives of Formula 17 provides the 1,3-dihydro-4-nitro-iso-benzofuran compounds of Formula 18. The nitro compounds of Formula 18 are reduced with hydrogen on a suitable catalyst, such as palladium, to give the 1,3-dihydro-4-amino-iso-benzofuran compounds of Formula 19.
