The invention relates to a process for preparing a substituted 2-amino-benz[cd]indole of the Formula I: ##STR1## The nitro group of a substituted 1-nitro-8-cyano-naphthalene compound is reduced to an amine group to form a substituted 1-amino-8-cyano-naphthalene compound, which is cyclized to form the substituted 2-amino-benz[cd]indole. The reduction and cyclization may be effected in a one-pot procedure using a reducing agent such as stannous chloride, which generates an acid that cyclizes the reduction product. The syntheses of the 1-nitro-8-cyanonaphthalene compound and its precursors are also described.

On réduit le groupe nitro d'un composé 1-nitro-8-cyano-naphtalène en groupe amine pour former un composé 1-amino-8-cyano-naphtalène substitué que l'on cyclise pour former le 2-amino-benz[cd]indole substitué. La réduction et la cyclisation peuvent s'effectuer selon une technique en un seul pot au moyen d'un agent de réduction tel que le chlorure stanneux qui génère un acide cyclisant le produit de réduction. Les synthèses du composé 1-nitro-8-cyano-naphtalène et de ses précurseurs sont également décrites.

The design, synthesis, and biochemical and biological evaluations of a novel series of 2,6-diaminobenz[cd]indole-containing inhibitors of human thymidylate synthase (TS) are described. The compounds are characterized by having either a pyridine or pyridazine ring in place of the (phenylsulfonyl)morpholinyl group of the known inhibitor N6-[4-(morpholinosulfonyl)benzyl]-N6-methyl-2,6-diaminobenz[ cd]indole
