Reaction Steps

To a solution of (5-Methyl-2-phenyl-2H-[1,2,3]triazol-4-yl)-methanol (0.25 g, 1.30 mmol) in 10 ml of toluene was added PBr3 (0.53 g, 1.90 mmol) and the reaction mixture was heated at 120° C. for 20 min under nitrogen atmosphere. After the completion of the reaction mixture (TLC monitoring), water (25 mL) was added and extracted with ethyl acetate (3×50 mL). The combined organics was washed with water, brine, dried (Na2SO4), filtered and concentrated to get the desired product (0.30 g, 90%) as a yellow solid.
