Compound (I) was prepared as previously reported (Garden et al., 2003). Crystals suitable for single-crystal X-ray diffraction were grown by slow evaporation of a solution in hexane-dichloromethane (1:1, v/v).
All the H atoms were located in difference maps, relocated in idealized positions, and treated as riding atoms with distances C—H 0.95 Å (aromatic), 0.98 Å (CH3) or 0.99 Å (CH2), N—H 0.91 Å and O—H 0.84 Å, and with Uiso(H) = kUeq(carrier), where k = 1.5 fo the hydroxyl and methyl H atoms and 1.2 for all other H atoms.
We report here the structure of the title compound (I) (Fig. 2), which is a precursor (Garden et al., 2003) of ethyl N-[2-(hydroxyacetyl)phenyl]carbamate (II), whose structure we reported recently (Garden et al., 2007).
The 1,3-dioxolane ring in (I) adopts a twisted conformation with ring-puckering parameters (Cremer & Pople, 1975) for the atom sequence (O21, C21, O23, C24, C23) of Q2 0.360 (2) Å and φ2 347.3 (2)°, with atom displacements from the mean plane indicative of a conformation twisted about the line joining atom O23 to the mid-point of the O21—C23 bond. The carbamate ester side chain adopts an almost planar, all-trans conformation, as indicated by the relevant torsional angles (Table 1). The conformation about the C2—C21 bond is such that atom O21 is close to the plane of the aryl ring: hence it seems unlikely that this conformation is materially influenced by the intramolecular N—H···O hydrogen bond (Table 2).
A single O—H···O hydrogen bond (Table 2) links pairs of molecules into cyclic dimers: the hydroxyl atom O22 at (x, y, z) acts as hydrogen-bond donor to the carbonyl atom O11 in the molecule at (1 - x, 1 - y, 1 - z), so generating by inversion an R22(18) ring (Bernstein et al., 1995) centred at (1/2, 1/2, 1/2) to which are fused two S(6) rings generated by the intramolecular N—H···O hydrogen bond (Fig. 3). Two dimers of this type lie in each unit cell, but there are no direction-specific interactions between the dimer units.
In the precursor compound (II) (Garden et al., 2007) all of the non-H atoms lie on a mirror plane in space group Pnma and the molecules are linked by a single C—H···O hydrogen bond into a simple C(6) chain.

We report here the structure of the title compound (I) (Fig. 2), which is a precursor (Garden et al., 2003) of ethyl N-[2-(hydroxyacetyl)phenyl]carbamate (II), whose structure we reported recently (Garden et al., 2007).
The 1,3-dioxolane ring in (I) adopts a twisted conformation with ring-puckering parameters (Cremer & Pople, 1975) for the atom sequence (O21, C21, O23, C24, C23) of Q2 0.360 (2) Å and φ2 347.3 (2)°, with atom displacements from the mean plane indicative of a conformation twisted about the line joining atom O23 to the mid-point of the O21—C23 bond. The carbamate ester side chain adopts an almost planar, all-trans conformation, as indicated by the relevant torsional angles (Table 1). The conformation about the C2—C21 bond is such that atom O21 is close to the plane of the aryl ring: hence it seems unlikely that this conformation is materially influenced by the intramolecular N—H···O hydrogen bond (Table 2).
A single O—H···O hydrogen bond (Table 2) links pairs of molecules into cyclic dimers: the hydroxyl atom O22 at (x, y, z) acts as hydrogen-bond donor to the carbonyl atom O11 in the molecule at (1 - x, 1 - y, 1 - z), so generating by inversion an R22(18) ring (Bernstein et al., 1995) centred at (1/2, 1/2, 1/2) to which are fused two S(6) rings generated by the intramolecular N—H···O hydrogen bond (Fig. 3). Two dimers of this type lie in each unit cell, but there are no direction-specific interactions between the dimer units.
