2,3-Dichloro-1,4-naphthoquinone was reacted with o-fluoroaniline, p-sulfadiazine, p-acetoanline, N,N-dimethyl-1,4-phenylenediamine as a nucleophilic substitution to form 2-chloro-3-(N-arylamino)-1,4-naphthoquinones (1.-6.) in good yield. 2,3-Dibromo-1,4-naphthoquinone was also reacted with o-fluoroaniline, m-aminobenzoic acid, m-chloroaniline, morpholine, p-acetoaniline, N,N-dimethyl-1,4-phenylenediamine as a nucleophilic substitution to give 2-bromo-3-(N-arylamino)-1,4-naphthoquinones (7.-12.). These new compounds are expected to have a biological activities such as anticoagulant, cytotoxic.
