SYNTHESIS OF AROMATIC PYRAZOLOPYRIDINE DERIVATIVES
Orlov, V. D.,Kiroga, Kh.,Kolos, N. N.
, p. 997 - 1001 (2007/10/02)
Cyclocondensation of chalcones with 5-amino-3-methyl-1-phenylpyrazole leads to the formation of 2,4-diaryl-5-methyl-7-phenyl-3,4-dihydropyrazolo-pyridines, which undergo aromatization upon treatment with N-bromosuccinimide.
