Ethanol → HCID 178494754, Verbindung

To a solution of phosphoric acid mono-(1-{4-[(S)-5-(acetylamino-methyl)-2-oxo-oxazolidin-3-yl]-2,6-difluorophenyl}-4-methoxymethyl-piperidin-4-yl)ester (5.0 g, 0.010 mol anhydrous ethanol (50 ml) at 25-30° C., under argon, was added L-arginine (1.76 g, 0.010 mol). The reaction mixture was stirred at 80-85° C. for 0.5 h. Water (5 ml) was added to the reaction mixture and stirring continued further for 1 h at 80-85° C. The reaction mixture was filtered and the filtrate evaporated under reduced pressure. Acetone (25 ml) was added to the residue and triturated. The solvent was decanted. This procedure was repeated twice with acetone (50 ml). Acetone after the third trituration was decanted and the residue dried under reduced pressure to obtain the product as off-white solid, 6.1 g, 91% yield. Aqueous solubility at pH 7 was >200 mg/ml.
