Compound: 4-Chloro-8-methylquinoline, is researched, Molecular C10H8ClN, CAS is 18436-73-2, about A mild and efficient method for the preparation of 3-(2′-aminoaryl)pyrazoles from 4-chloroquinolines. Author is Borges, Julio C.; de Oliveira, Cesar D.; da Silva Pinheiro, Luiz C.; Marra, Roberta K. F.; Khan, Misbahul Ain; Wardell, James L.; Wardell, Solange M. S. V.; Bernardino, Alice M. R..
The authors described a mild and efficient method for the formation of 3-(2′-aminoaryl)pyrazoles in excellent yields from reactions of 4-chloroquinolines with hydrazine. These heterocyclic ring opening reactions occur under much milder conditions then previously described. The structures of the compounds were determined by spectral data and confirmed by x-ray diffraction anal. of 3-(2′-amino-3′-methylphenyl)pyrazole [monoclinic, C2, a 25.9750(3), b 9.5820(6), c 7.8299(7) Å, β 107.541(3)°, V 1858.2(2) Å3, Z 8].
