Abstract

The reaction of lauroyl isothiocyanate and 2-amino-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carbonitrile was used to synthesize the title compound 2. Compound 2 could serve as the main building block in the synthesis of many target heterocyclic systems. Various fused pyrimidines were synthesized in the reactions of compound 2 with sodium ethoxide, hydrazine hydrate, phenyl hydrazine, ethyl carbazate, thiourea, and/or 2-aminothiophenol. The structures of the synthesized compounds were confirmed by microanalytical and spectral data.
