To a solution of 7.9 g 1-chloro-4-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranos-1-yl)-2-(4-acetoxy-benzyl)-benzene in 150 mL methanol is added 25 mL 4 M aqueous potassium hydroxide solution. The solution is stirred at room temperature for 1 h and then adjusted to pH 5 with 4 M hydrochloric acid. Most of the methanol is evaporated and the remaining solution is extracted with ethyl acetate. The combined extracts are dried over sodium sulfate and the solvent is removed in vacuo.
