Procedure

Triethylamine (0.2 mL, 1.38 mmol, 3 equiv), followed by 3-bromo-1-propanol (60 μL, 0.69 mmol, 1.5 equiv), were added to a stirred solution of crude 4-pentyl-pyrrolidine-2-carboxylic acid [2-methyl-1-(3,4,5-trihydroxy-6-methylsulfanyl-tetrahydro-pyran-2-yl)-propyl]-amide (192.5 mg, 0.46 mmol, 1 equiv), prepared as in Example 10, in anhydrous acetonitrile (2 mL), under nitrogen. The resulting mixture was stirred at rt for 18 h and evaporated to dryness. The residue obtained was purified by chromatography over silica gel with an eluent of 5% methanolic ammonia in dichloromethane. The desired fractions were pooled together, evaporated to dryness, and lyophilized to furnish the title compound as a white fluffy powder (13.5 mg, 6%).
