Alkylation of 1,8-bis(methylamino)naphthalene with difunctional reagents leads to a series of 1,5-dimethylnaphtho[1,8-bc]-1,5-diazacycloalkanes(1)–(5), to 1,5-dimethylbenzo[g]naphtho[1,8-bc]-1,5-diazacyclononane (6), and to 1,5-dimethylnaphtho[1,8-bc]-1,5-diaza-8-oxacyclodecane (7). A variety of attempts to develop a selective preparation of 1,8-bis(methylamino)naphthalene are reported. The preparation
