Versuchsvorschrift

This derivative was prepared in a manner similar to Example 1, using 2.6 g (0.005 mol) of Raloxifene HCl, 2 g (0.02 mol) of triethylamine, 20 mg of DMAP, and 3.2 g (0.01 mol) of linolenoyl chloride in 250 mL of THF. The final product was chromatographed on a silica gel column eluted with EtOAc-hexane (8:2). This yielded 3.21 g of the title compound as clear oil.
