Reaction Steps

5-Hydroxy-2-methylbenzotellurazolium chloride (Example 17) (7.45 g) was dissolved in warm water (300 ml) and a slurry of sodium bicarbonate (8 g) in water was added slowly. The free base product separated as a cream colored amorphous solid, which was collected by filtration, washed with water, and dried in a vacuum over Drierite® brand calcium sulfate drying agent, yield 6.3 g. The material was then recrystallized from isopropanol (50 ml) to give a recovery of ≃4.0 g, m.p. 190°-192° C.
