الإجراء التجريبي

A 0° C. solution, under argon, of 0.123 g of product from Example 139 in 1.0 ml of dry chloroform is treated with 51.1 microliter of boron trifluoride etherate and 0.193 g of tetra n-butylammonium iodide. The reaction mixture is stirred at room temperature overnight and concentrated in vacuo. The residue is purified by chromatography (silica gel: 0-100% ethyl acetate/hexane) to give 0.079 g of the desired product.
