Procedure

Using the procedure of Example 3, 55 mg of 50% sodium hydride and 355 mg of the product of Example 13 were reacted and 2.5 ml of dimethylsulfoxide were added dropwise over 20 minutes. Rinsing was carried out with 0.5 ml of dimethylsulfoxide and 20 minutes after the release of hydrogen had stopped, 0.41 g of 4-iodo-butoxytrimethylsilane were added. The reaction medium was poured into 25 ml of water containing 0.1 g of monopotassium phosphate and extraction was carried out 3 times with ether. The organic phase was washed with water, then with salt water and dried. The resultant product was taken up in 10 ml of methanol and 1 ml of 2N hydrochloric acid and left for 30 minutes. It was poured into 30 ml of 50% sodium chloride and extraction was carried out 3 times with ethyl acetate. The extracts were washed with salt water and dried. Purification was carried out on silica with methylene chloride-acetone: 9-1 as eluant to obtain 317 mg of the expected product (white crystals) melting at 139°-140° c.
