Helical aromatics (1) were synthesized via one step in good quantity by solvent-free condensation of N,N′-p-phenylenediamine (2) and various carboxylic acids in the presence of a Lewis acid. Microwave irradiation greatly facilitated the condensation react

A new and reliable procedure for the multigram-scale preparation of 2-methyl-1-phenyl-5-phenylaminobenzimidazole (6) is reported.Bernthsen thionation of 6 leads to 2-methyl-3-phenyl-6H-imidazophenothiazine (9), whose structure was established throu
