Abstract

The synthesis of the title compound6 c, starting with the condensation of o-phenylenediamine and methyl 4-oxotetrahydrothiophene-3-carboxylate (1) to 1.3.4.9-tetrahydrothieno[3.4-b] [1.5]benzodiazepin-10-one (2), is described.

The structures of other products of this condensation, 1.3-dihydro-1-[3-(2.5-dihydrothienyl)]-benzimidazol-2-one (3) and 1.3-dihydro-1-[3-(2.3-dihydrothienyl)]-benzimidazol-2-one (4), are confirmed by their1H-NMR-spectra and by the1H-NMR-spectra of their desulfurization products.
