The Mannichreaction of cytosine, paraformaldehyde and cyclic secondary amines in the presence of acetic acid gives 5-(4′-morpholinyl)methylcytosine, 5-(1′-piperidinyl)methylcytosine, 5-(1′-pyrrolidinyl)methylcytosine, 5-(4′-methyl-1′-piperidinyl)methylcytosine, 5-(3′-methyl-1′-piperidinyl)methylcytosine and 5-(2′-methyl-1′-piperidinyl)methylcytosine. These products are quite different from those obtained
