Participants

Reaction Steps

Dissolve the crude [1-(3,5-bis-trifluoromethyl-benzyl)-5-phenyl-1H-[1,2,3]triazol-4-yl]-methanol (3.90 g, 0.0097 mol) in DMSO (30 mL) and add N,N-diispropylethylamine (6.77 mL, 0.039 mol). To this solution add sulfur trioxide pyridine complex (3.09 g, 0.019 mol) in DMSO (30 mL) and stir at RT. After 2 h., add the reaction mixture to EtOAc (150 mL) and 0.5 N HCl (200 mL), and separate the layers. Extract the aqueous layer with EtOAc (50 mL). Combine the organic layers and wash with saturated, aqueous sodium bicarbonate (100 mL) and 1.0 N HCl (100 mL). Dry the organic layer over MgSO4, filter, and concentrate to give the title compound. 1H NMR (500 MHz, DMSO) δ 9.91 (s, 1H), 8.02 (s, 1H), 7.69 (s, 2H), 7.55–7.49 (m, 5H), 5.86 (s, 2H); MS (m/e): 400 (M++1).
