Versuchsvorschrift

2-Methylbenzotellurazole (Example 18) (0.81 g, 0.0033 mole) was dissolved in dichloromethane (30 ml). The solution of ethoxycarbonylmethyl trifluoromethanesulfonate (0.004 mole) in carbon tetrachloride prepared as described above, was placed in a dropping funnel and added to the benzotellurazole solution at room temperature under a nitrogen atmosphere. After the addition was complete, the mixture was stirred at room temperature, while maintaining a nitrogen atmosphere for 22 hours. The solid was isolated by filtration and dried at room temperature under vacuum. Yield was 0.62 g (39% of theory) of a white powder, m.p. 156°-158° C. The C, H, N and S elemental analyses and the infrared, nuclear magnetic resonance, and mass spectra were all in agreement with that expected for the structural formula.
