Abstract
2-Amino, 2-amino-3-methyl-, and 4-aminopyridine react with α-chloro-α-isonitrosoacetone at the heteroring nitrogen atom to give salts, which are converted to imidazo[1,2-a] pyridines or, in the case of 4-aminopyridine, to 1-(1-oximino-2-oxopropyl)-4-pyridoneimine when they are treated with alkali. Acetylpyridylurea was obtained from chloroisonitrosoacetone and 2-aminopyridine in pyridine.
