Sodium Bicarbonate → HCID 13931216, compound

Participants

Reaction Steps

2-Methyl-5-methylthiobenzotellurazolium chloride (Example 16) (11.5 g=0.035 mole) was suspended in water and sodium bicarbonate in excess of that stoichiometrically required was added. The free base was extracted into dichloromethane. The organic solution was washed with saturated aqueous sodium sulfate, dried, and evaporated in vacuum to a yellow oil (9.06 g). Upon addition of isopropanol (40 ml) the oil crystallized spontaneously to almost white needles to give 8.18 g, 79.8% of theory, m.p. 64°-67° C.
