Procedure
To a solution of 2-methylbenzotellurazole (Example 18) (0.81 g, 0.0033 mole) in acetone (25 ml), chilled in an ice bath, was added slowly with stirring 55 mole percent hydriodic acid (1 ml). The product began precipitating from solution. After the addition was complete, the mixture was stirred at ice bath temperature for approximately 10 minutes. The solid was isolated by filtration, washed with diethyl ether, and dried under vacuum at room temperature. Yield 1.13 g (92%) of yellow powder, m.p. 209°-211° C. The C, H, and N elemental analyses and the infrared, nuclear magnetic resonance, and mass spectra of the sample were in agreement with that expected for the structural formula.
