Boron tribromide → HCID 21188009, compound

Participants

Reaction Steps

1,1 g of 1-(2-methoxyphenyl)-3-phenyl-1,2,4-triazole (cf. Example 2) are dissolved in 40 ml of dichloromethane and a solution of 1 ml of BBr3 in 10 ml of dichloromethane is added dropwise. After 3-4 hours stirring at ambient temperature the mixture is poured onto ice water and the organic phase is separated off. The remaining aqueous phase is again extracted with dichloromethane. After the collected dichloromethane phases have been dried over Na2SO4 the solvent is distilled off. 1 g (96%) of the title compound are left (melting point: 148-154° C.).
