Reaction Steps

To a solution of the compound of Example 17 (0.353 mmol) dissolved in 2.5 ml of pyridine there is added a solution of triphenylphosphine (1.415 mmol) and then carbon tetrachloride (0.707 mmol). The mixture is stirred at ambient temperature for 2.30 hours and is then poured into water. The mixture is extracted with ethyl acetate and the organic phase is washed successively with a 1N aqueous solution of hydrochloric acid, water and a saturated solution of NaHCO3. After evaporating off the solvent and then purifying by chromatography over silica gel (ethyl acetate), the expected product is isolated.
