The compound (IV) was prepared according to the procedure described in Example 1 for the synthesis of (XIX), starting from 5 g of the chloride of acetylsalicylic acid, 3.5 ml of TEA and 2.17 g of 1.10-decandiol. The product was purified by chromatography utilizing an eluent mix constituted by ethylether/hexane 7:3 (v/v). The intermediate fractions were collected, the solvent was evaporated under reduced pressure and a solid residue was obtained which, trirurated with isopropyl ether, produced 1.37 g of 1.10-decandiol bis-acetylsalicylate (IV) with m.p.=75° C.
