Reaction Steps

To a solution of {1-[(3,4-dichlorophenyl)methyl]-1H-1,2,3-triazol-4-yl}methanol (Intermediate 16) (0.17 g, 0.66 mmol) in DCM was added PBr3 (125 μL, 2 eq) and the reaction was stirred at room temperature for 3 hours. Water was added, followed by solid NaHCO3. The organic phase was dried over sodium sulphate and evaporated. The title compound was obtained as a colorless oil (0.21 g, 99%) and used in the next step without purification. LC/MS: m/z 320 (M−H)+. Rt: 2.13 min.
