Procedure
2 ml (9.6 mmoles) of hexamethyldisilazane were added to a refluxing mixture of 1.83 mg (10 mmoles) of saccharin, 10 mg (0.02 mmole) of di-4-nitrophenyl N-(4-toluenesulfonyl)-phosphoramidate and 20 ml of acetonitrile under dry nitrogen and the ammonia evolved was led into water by the nitrogen stream and was titrated with 1 N sulfuric acid. The calculated amount of ammonia was evolved within 0.5 hour and the solvent and other volatile materials were removed by evaporation in a rotating film evaporator. Then, the residue was dried under vacuum to obtain 2.50 g (98%) of trimethylsilylsaccharin melting at 90°-92° C.
