2,3-Dibromo-1,4-naphthoquinone was reacted with p-aminobenzoic acid, 2-aminopyridine, 2-amino-4-metylpyridine, m-nitroaniline, sulfathiazol, p-chloroaniline, phenetidine and 2-bromo-3-(N-arylamino)-1,4-naphthoquinones($1{\sim}8$). 2,3-Epoxy-2,3-dihydro-1,4-naphthoquinone was also reacted with p-amonobenzoic acid, p-toluidine, p-chloroaniline, m-chloroaniline, m-nitroaniline, p-phenetidine, N,N-dimethyl-1,4-pheylenediamine as a ring opening and dehydogenation to form 2-hydroxy-3-(N-arylamino)-naphthoquinones ($9{\sim}16$) in good yield. These new compounds($1{\sim}16$) are expected to have a biological activities such as anticoagulant and cytotoxic.
