title: Ethyl 7-chloro-methyl-5-(2-chloro-phen-yl)-7-hydr-oxy-2-methyl-sulfanyl-4,5,6,7-tetra-hydro-1,2,4-triazolo[1,5-a]pyrimidine-6-carboxyl-ate.
abstract: In the title compound, C(16)H(18)Cl(2)N(4)O(3)S, the five-membered ring is almost planar [maximum deviation = 0.011 (3) Å] and the six-membered ring adopts an envelope conformation. In the crystal structure, N-H⋯N, O-H⋯N and C-H⋯O inter-actions link mol-ecules into a three-dimensional network.
