Methyl acetyl urea, CH 3 NH CO NH000H 31 is formed by the action of potash on a mixture of bromine (I mol.) and acetamide (2 mols.) (A.
It condenses with acetic anhydride to form a methyldiphenyl triazine, acetamide being also formed; with acetyl-acetone to form dimethylphenyl pyrimidine (A.
On the other hand, they show faintly acid properties since the hydrogen: of the amido group can be replaced by metals to give such compounds as mercury acetamide (CH 3 CONH) 2 Hg.
It forms hydroxyhydrocollidine when heated with acetamide and anhydrous zinc chloride (F.
