1-(2-Hy-droxy-eth-yl)-3-phenyl-thio-urea

Abstract

The title compound, C9H12N2OS, was obtained unexpectedly in a multicomponent reaction of an equimolar ratio of phenyl isothio-cyanate, malononitrile and amino-ethanol. The-C(H 2)-N(H)-(C=S)-N(H)-methyl-thio-urea-methane group is almost normal to the phenyl ring, with a dihedral angle of 71.13 (9)°. The N-C-C-O torsion angle is 72.8 (2)°. In the crystal, mol-ecules are connected by N-H⋯O, O-H⋯S and N-H⋯O hydrogen bonds, forming a three-dimensional network.
