Ethyl 2-(3-benzoyl­thio­ureido)acetate

Abstract

The title compound, C₁₂H₁₄N₂O₃S, adopts a cis–trans geometry of the thio­urea group and is stabilized by intra­molecular hydrogen bonds between the carbonyl O atoms and the H atom of the thio­amide group and by a C—H⋯S interaction. Mol­ecules are linked by two inter­molecular hydrogen bonds (C—H⋯O and N—H⋯O), forming a one-dimensional chain parallel to the c axis.

Comment

Some thiourea derivatives of amino acids, such as 2-[3-(4-methoxbenzoyl) thioureido]-3-methylbutyric acid (Ngah et al., 2005), 3-[3-(4-methoxybenzoyl) thioureido]propanoic acid and (Ngah et al., 2005) and 2-(3-benzoylthioureido) ethanoic dimethyl sulfoxide solvate (II) (Ngah et al., 2005) have been synthesized and their structures have been reported. We are interested to synthesize a series of esters containing thiourea moiety by catalytic transesterification. The title compound, (I), is an ester of (II).

The molecule maintains the cis-trans geometry of the thiourea moiety (Fig. 1). The phenyl ring (C1—C6) and (S1/N1/N2/O1/C6/C7/C8/C9) fragments are each planar with maximum deviation of 0.031 (2)Å for C6 atom from the least square plane of the later. The dihedral angle between the two planes is 26.53 (8)°. The bond lengths and angles are in normal ranges (Allen et al., 1987). There are three intramolecular hydrogen bonds, N2—H2···O1, N2—H2···O2 and C9—H9B···S1. As a result, one pseudo-six-membered ring (N2/H2/O1/C7/N1/C8) and two pseudo-five-member ring (N2/H2/O2/C10/C9) and (C9/H9B/S1/C8/N2) are formed, respectively. In the crystal structure, the molecules are linked by N1—H1···O2 and C9—H9B···S1 intermolecular hydrogen bonds to form one dimensional chain along the c axis (Fig. 2).

Experimental

2-(3-Benzoylthioureido)ethanoic acid was prepared as reported (Ngah et al., 2005). 2.38 g (10 mmol) of 2-(3-benzoylthioureido)ethanoic acid and 2.45 g (10 mmol) of lanthanum chloride were refluxed in methanol for 17 h. The resulting solution was left for one day at room temperature. Recrystallization of the resulting solid from dichloromethane gave colourless crystals of (I) [yield: 70%]).

Refinement

All H-atoms attached to C were positioned geometrically and refined using a riding model U_iso=1.2U_eq (C) for aromatic 0.93 Å, U_iso = 1.2U_eq (C) for CH₂ 0.97 Å and U_iso = 1.5U_eq (C) for CH₃ 0.97 Å. Hydrogen atoms attached to N were also positioned geometrically and allowed to ride on their parent atoms and with U_iso(H) = 1.2U_eq(N) for N–H 0.86 Å.

Special details

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.

Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger.
