title: 2-Morpholino-4-oxo-4,5-dihydro-thio-phene-3-carbonitrile.
abstract: The title compound, C(9)H(10)N(2)O(2)S, was obtained from the treatment of ethyl 4-cyano-3-hydr-oxy-5-morpholinothio-phene-2-carboxyl-ate with concentrated HCl. The mean plane of the essentially planar dihydro-thio-phene ring is almost orthogonal to the mirror plane of the N-morpholine substituent, making a dihedral angle of 87.2 (2)°.
