Synthesis of 5-Amino-1,3-dimethylpyrazol-4-yl Aryl Ketones
DeWald, H. A.
, p. 1175 - 1176 (2007/10/02)
A convenient preparation of 5-amino-1,3-dialkylpyrazol-4-yl heterocyclic ketones is reported.They are prepared from the reaction of heterocyclic esters with the di-lithio derivative from N-(4-bromo-1,3-dimethyl-1H-pyrazol-5-yl)benzamide (1).
