Abstract 2,6‐Dihydroxy‐4‐methyl‐3‐pyridinecarbonitrile is converted via its 2,6‐dichloro analog into the corresponding 2‐amino‐6‐chloro, 2‐chloro‐6‐amino, and 2,6‐diamino derivatives. The last reacts with benzene‐sulfonyl chloride to yield a tris‐sulfonyl derivative, the structure of which is demonstrated by X‐ray analysis.
