چکیده
In the title compound, C16H17NO3S, a thio-phene derivative with amino phenyl, acetyl, methyl and ethyl carboxyl susbtituents attached to a central thio-phene ring, the phenyl and thio-phene rings form a dihedral angle of 36.92 (9) Å. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond, which forms an S(6) ring motif.

In the title thio-phene derivative, C13H18N2O3S, the dihedral angles between the thio-phene ring and the [(di-methyl-amino)-methyl-idene]amino side chain (r.m.s. deviation = 0.009 Å) and the -CO2 ester group are 3.01 (16) and 59.9 (3)°, respectively. In the crystal, inversion dimers linked by pairs of C-H⋯O hydrogen bonds generate R 2 (2)(16) loops. The dimers are linked by another weak C-H⋯O i...
