الإجراء التجريبي

Following the procedure described for the preparation of Example 12, starting from 0.10 g (0.25 mmol) of the compound obtained in Example 30 and 0.18 g (1.20 mmol) of sodium iodide in 3 ml of acetone at room temperature, then purification by chromatography on silica gel (eluant: diethyl ether/pentane, 1.5:1), 0.079 g (0.22 mmol) of the desired product in the form of a pale-yellow-coloured solid is obtained.
