Procedure
The compound (II) was prepared according to the procedure described for the synthesis of triethylenglycol bis-acetylsalicylate (XIX), starting from 2 g of the chloride of acetylsalicylic acid, 0.93 g of tetraethylenglycol and 1.5 ml of trietylamine. The product was purified on silica gel chromatography utilizing an eluent mix constituted by methylene chloride/ethyl acetate 1:1 (v/v). The intermediate fractions were collected, the solvent was evaporated under reduced pressure and 0.6 g of tetraethylenglycol bis-acetylsalicylate (II) were obtained.
