2-Amino-N-(furan-2-ylmethyl)-5,6-dihydro-4H-cyclopenta[b]thiophene-3-carboxamide

Abstract

In the title compound, C13H14N2O2S, the dihedral angle between the furan and cyclopentathiophene groups is 89.88 (14)°. The carboximidamide unit is in an anticlinal conformation with respect to the cycloheptathiophene moiety and an intramolecular N—H...O hydrogen bond closes an S(6) ring. In the crystal, N—H...O hydogen bonds link the molecules into [010] C(6) chains and a very weak C—H...O interaction is also observed.
