실험 절차
2,5-Dimethylnaphtho[1,2-d]tellurazole (Example 27) (0.93 g=0.003 mole) was dissolved in PG,63 dry dichloromethane, and methyl trifluoromethanesulfonate (0.33 ml=0.003 mole) was added. The flask was sealed and kept over a weekend. Bright yellow plates (0.88 g, 61% of theory) formed. The product was recrystallized from 10 ml of acetone by addition of 20 ml of diethyl ether. The melting point was 224°-230° C. The mass and nuclear magnetic resonance spectra were in agreement with that expected for the structural formula.
