To 1,1,1-trifluorobutan-2-one (5.0 g, 39.7 mmol, 1.0 equiv) was slowly added trimethylsilylcyanide (4.7 g, 47.6 mmol, 1.2 equiv) and the resulting mixture stirred overnight at ambient temperature. To the resulting mixture was added water (80 mL) followed by zinc chloride (5.4 g, 39.7 mmol, 1.0 equiv) and sodium azide (3.1 g, 47.1 mmol, 1.2 equiv) and the mixture was heated at 80° C. for three hours. The mixture was cooled to room temperature and the precipitate was filtered and dried in vacuo to afford 1,1,1-trifluoro-2-(2H-tetrazol-5-yl)butan-2-ol (3-3) as a white solid. LRMS m/z (M+H)+ 197.0 found, 197.1 required.
