title: Ethyl 2-(3,3-dibutyl-thio-ureido)-4,5,6,7-tetra-hydro-benzo[b]thio-phene-3-carboxyl-ate.
abstract: In the title compound, C(20)H(32)N(2)O(2)S(2), the cyclo-hexene ring is disordered over two half-boat conformations with occupancy factors of 0.71:0.29. One n-butyl chain is also disordered over two positions with occupancy factors of 0.83:0.17. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond.
