The synthesis of six novel fluorinated potential prodrugs for antibody-directed enzyme prodrug therapy is described. The [2- and 3-fluoro-4-[bis(2-chloroethyl)amino]benzoyl]-L-glutamic acid (9 and 21), their bis(mesyloxy)ethyl derivatives (7 and 19), and their chloroethyl (mesyloxy)-ethyl derivatives (8 and 20) are bifunctional alkylating agents in which the activating effect of the ionized carboxyl
