A series of 3-amino-4-(p-aminophenyl)isoquinolines bearing the bis (2-chloroethyl)amino group was synthesized as potential CNS antitumor agents. Diol precursors 1e and if were prepared by the treatment of 1b and 1e with ethylene oxide. Diol precursors 5a-c and 9 were prepared by the treatment of 4a-c and 8 with diethanolamine. The reaction of these diols with SOCl₂ yielded target mustards 10-15 which were evaluated in the intraperitoneal murine L1210 tumor. No intermediates or target mustards were active in this tumor system.
