実験手順

5,6-Dimethoxy-2-methylbenzotellurazole (Example 19) was dissolved in chloroform (150 ml). A stoichiometric amount of ethyl trifluoromethanesulfonate was added, and the solution was refluxed for two hours under a condenser protected with a drying tube. After cooling the solution was poured slowly into cold diethyl ether (700 ml) with rapid stirring. The product crystallized and was collected by filtration. Yield 19.3 g (77.3% of theory).
