Synthesis of l-Methyl-4-(5-14C-3-methyl-5-isoxazolyl) pyridinium Chloride
Received on 21st November 1968 l-Methyl-4-(3-methyl-5-isoxazolyl)pyridinium chloride (1) has been found to display interesting hypoglycemic activity in laboratory animals, and is currently undergoing extensive evaluation as a potential antidiabetic drug. To facilitate the study of the bodily distribution and metabolism of 1, a radiolabelled sample was required.
