Abstract
2-Hydrazino-4-methylpyrimidine (I) prepared by Shiho, et al. and by the present authors differed in their respective melting points. The one prepared by the author gave 4-methylpyrimidine (X) by copper sulfate, 2-hydroxy-4-methylpyrimidine (XI) by oxidation with KMnO4, and hydrazine and (XI) by hydrolysis with hydrochloric acid so that this compound could not be other than (I).
