Heterocycles via Mannich Condensation, VI: Syntheses of 2-Amino-3-pyridylphenyl Ketones
Soellhuber-Kretzer, Monica,Troschuetz, Reinhard,Roth, Hermann J.
, p. 199 - 207 (1982)
The ethyl 2-benzoylacetimidates 1a-c and 2-benzoylacetamidine (2a) exist in solution as enols.Ketonic Mannich bases condense with 1a-c and 2a to yield 2-amino-3-pyridylphenyl ketones.
