Boron tribromide → HCID 18318016, compound

Participants

Reaction Steps

12 ml of 1M boron tribromide in dicloromethane are added at −30° C., under an inert atmosphere, to a solution of 2 g of the compound obtained in Example 7 in 50 ml of dichloromethane. After reaction for two hours at ambient temperature, the reaction mixture is hydrolysed with 1 ml of a saturated ammonium chloride solution. The precipitate obtained is filtered off, washed with water and then dried, enabling the expected product to be isolated.
