Reaction Steps

The compound of Example 351 (4.70 mmol) is dissolved in dichloromethane (30 ml). After adding CBr4 (2.02 g; 6.10 mmol), the reaction medium is cooled down to 0° C. PPh3 (1.48 g; 5.63 mmol) is added by fractions then the mixture is left to return to ambient temperature. The reaction medium is then poured into ice-cold water before being extracted with dichloromethane. The organic phase is washed with salt water before being dried over magnesium sulphate, filtered and concentrated under vacuum. The crude oil obtained is sufficiently pure to be used directly in the following stage.
