Journal of Heterocyclic Chemistry, 1985
AbstractThe reaction of 3‐(methylthio)‐5‐carbethoxy‐1,2,4‐triazine (5) with ammonia was found to yield products from not only ammonia but also methanethiolate displacements. An account of the transformations and the products observed is given. The 3‐position of 3,6‐bis(methylthio)‐5‐carbamoyl‐1,2,4‐triazine (7) was shown to be more reactive than the 6 ...
