Condensation of 4‐amino‐6‐chloro‐2‐methoxypyrimidine (I) with p‐nitrobenzenesulfonyl chloride (II) gave, in addition to 6‐chloro‐2‐methoxy‐4‐( p ‐nitrobenzenesulfonamido)pyrimidine (III), two abnormal by‐products, the structures of which were assigned as 1 ‐[2‐methoxy‐4‐( p ‐nitrobenzenesulfonamido)pyrimidine‐6‐yl]pyridinium N,N ‐betaine (IV) and N ‐( p ‐nitrobenzene‐sulfonyl)‐β‐ureido‐β‐pyridinium acrylamide N,N ‐betaine (V).
