Crystal structure of methyl 4-(2-fluoro­phenyl)-6-methyl-2-sulfanylidene-1,2,3,4-tetra­hydro­pyrimidine-5-carb­oxy­late

In the title compound, C(13)H(13)FN(2)O(2)S, the pyrimidine ring adopts a twist-boat conformation with the MeCN and methine-C atoms displaced by 0.0938 (6) and 0.2739 (3) Å, respectively, from the mean plane through the other four atoms of the ring. The 2-fluoro­benzene ring is positioned axially and forms a dihedral angle of 89.13 (4)° with the mean plane through the pyrimidine ring. The crystal structure features N—H⋯O, N—H⋯S and C—H⋯O hydrogen bonds that link mol­ecules into supra­molecular chains along the b axis. These chains are linked into a layer parallel to (10-1) by C—H⋯π inter­actions; layers stack with no specific inter­actions between them.
