Procedure

2-Methylbenzotellurazole (Example 18) (0.81 g, 0.0033 mole) was dissolved in dichloromethane (25 ml). The solution of benzyl trifluoromethanesulfonate (0.004 mole) in carbon tetrachloride, prepared as described above, was placed in a dropped funnel and added at room temperature under a nitrogen atmosphere to the benzotellurazole solution. Stirring was continued for 18 hours at room temperature after the addition was complete, maintaining a nitrogen atmosphere. The solid was isolated by filtration, washed with diethyl ether, and dried at room temperature under a vacuum. Yield 0.30 g (19% of theory) of a white powder, m.p. 120°-122° C. The infrared, nuclear magnetic resonance, and mass spectra of this compound were in agreement with that expected for the structural formula.
