23.4 ml (0.11 mole) of hexamethyldisilazane were added to a mixture consisting of 10.35 g (0.15 mole) of 1,2,4-triazole and 127 mg (0.75 mmole) of saccharin heated to 126° C. and evolution of ammonia started immediately. After refluxing for 30 minutes, the calculated amount of ammonia was evolved as determined by the method described in Example 1A. Vacuum distillation yielded 19.37 g (91.6%) of 1-trimethylsilyl-1,2,4-triazole boiling at 76.5°-78.0° C. at 12 mm Hg and nD 25=1.4592.
