実験手順
5,6-Dimethoxy-2-methylbenzotellurazole (Example 19) (1.0 g, 0.033 mole) was dissolved in dichloromethane (25 ml). The solution of 2-propyn-1-yl trifluoromethanesulfonate, prepared as described above, was added from a dropping funnel under a nitrogen atmosphere. After completion of the addition the mixture was stirred for 16 hours at room temperature. The solid was isolated by filtration, washed with diethyl ether, and dried under vacuum at room temperature. Yield, 1.14 g (70% of theory). The infrared, nuclear magnetic resonance, and mass spectra were in agreement with that expected for the structural formula.
