Procedure

To oritavancin bisphosphoric acid salt (5, 180 mg, 0.0905 mmol) in 1,4-dioxane (2 mL) and H2O (2 mL) was added NaHCO3 (25 mg, 0.29 mmol) and the mixture was stirred until all of 5 had dissolved. A solution of 34 (135 mg, 0.164 mmol) in 1,4-dioxane (3 mL) was added and the resulting solution was stirred at room temperature overnight. The product was precipitated by the addition of H2O and collected by filtration. The crude product was purified by C18 reversed phase chromatography on a Biotage™ flash chromatography system (30% to 80% MeCN in 0.2% TEA/phosphate pH 3) to give 37 (135 mg, 55%, based on the di-phosphoric acid salt) as a white solid: ESI-MS (M+2H) calculated for C120H157Cl3N14O38 1256.0. found 1255.4
