A dried 100-ml round-bottomed flask was charged with 2.43 g (10 mmol) of ethyl 5-bromo-2-methylbenzoate, 30 ml of dried THF and a magnetic bar, flushed with nitrogen and sealed with rubber septum. The flask was cooled with an ice-water bath, then stirring was initiated. Into the flask was slowly added 7.0 ml (21 mmol; 3.0 M in THF) of methyl magnesium chloride through syringe. After addition, the reaction mixture was stirred at this temperature for half an hour. The reaction mixture was poured into 200 ml of cooled water followed by addition of 200 ml of dichloromethane, and the reaction mixture was stirred and filtered off through a pad of celite. The filtrate was collected and the organic phase was separated. The aqueous phase was back-extracted with another 100 ml of dichloromethane, and the combined extracts were washed with saturated brine, dried over sodium sulfate and evaporated on a rotary evaporator to afford the crude product as a white solid, which was triturated with petroleum ether to furnish the pure product as colourless crystals after drying in vacuo at room temperature. Crystals suitable for diffraction were obtained by slow evaporation of a solution of the title compound in petroleum ether/dichloromethane (1:5 v/v) at room temperature.
All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.95–0.98 Å, O—H = 0.84 Å, and with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(C, O) for methyl and hydroxyl H atoms.
The title compound, whose
is reported herein, is an important intermediate for the synthesis of SGLT2 inhibitors possessing potent antihyperglycemic activity (Gao et al., 2010; Meng et al., 2008; Wang et al., 2010).The
of the title compound consists of four independent molecules of similar geometry (Fig. 1). All bond lengths and angles are not unusual. In the crystal packing, the independent molecules are linked by intermolecular O—H···O hydrogen bonds into tetramers (Table 1).The title compound is an intermediate for the synthesis of SGLT2
inhibitors, which possess potent antihyperglycemic activity, see: Gao et al. (2010); Meng et al. (2008); Wang et al. (2010).

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. |

The title compound, whose crystal structure is reported herein, is an important intermediate for the synthesis of SGLT2 inhibitors possessing potent antihyperglycemic activity (Gao et al., 2010; Meng et al., 2008; Wang et al., 2010).
The asymmetric unit of the title compound consists of four independent molecules of similar geometry (Fig. 1). All bond lengths and angles are not unusual. In the crystal packing, the independent molecules are linked by intermolecular O—H···O hydrogen bonds into tetramers (Table 1).
