Abstract
Nucleophilic substitution of methoxy groups in 4,11-dimethoxynaphtho[2,3-f]indole-5,10-dione by the action of primary and secondary alkylamines, or arylamines leads to the formation of N-alkyl or N-aryl derivatives of 4,11-diaminonaphtho[2,3-f]indole-5,10-dione respectively. 4,11-Diamino-1H-naphtho-[2,3-f]indole-5,10-dione is obtained by the dealkylation of 4,11-bis[(1-phenylethyl)amino]-1Hnaphtho[ 2,3-f]indole-5,10-dione in the presence of a Lewis acid (BBr3).
