反応手順
4-n-butylbenzenesulfonic acid is prepared by sulfonating 4n-butylbenzene with concentrated sulfuric acid at 180° C. as in previous reactions. Nitration of this compound with a mixture of sulfuric acid and nitric acid on a steam bath yielded 3-nitro-4-n-butylbenzenesulfonic acid. Hydrogenation of this in 50% ethanol/water over palladium on charcoal afforded 3-amino-4-n-butylbenzenesulfonic acid. Structural verification was obtained by carbon magnetic resonance, proton magnetic resonance and infra-red analysis.
