1-[3-(2-Methyl-4-phenylquinolin-3-yl)-5-phenyl-4,5-dihydro-1H-pyrazol-1-yl]-propane-1-one

Abstract

A novel compound, 1-[3-(2-methyl-4-phenylquinolin-3-yl)-5-phenyl-4,5dihydro-1H-pyrazol-1-yl]-propane-1-one (3) has been synthesized by cyclocondensation of (E)-1-(2-methyl-4-phenylquinolin-3-yl)-3-phenylprop-2-en-1-one (2) and hydrazine hydrate in propionic acid. The structure of this compound was established by elemental analysis, IR, 1 H-NMR, 13 C-NMR and MS data.

“…All IR spectra were performed on Shimadzu FT-IR-8201 PC spectrophotometer (Constantine, Algeria) and only significant absorption-band frequency is cited. 1 H-NMR and 13 C-NMR spectra were recorded in deuterated chloroform on a Brüker Avance DPX 250 spectrometer (Constantine, Algeria) at 250 MHz for proton and at 62.9 MHz for 13 C. Chemical shifts are given in ppm and J values in Hertz (Hz). The mass spectrum was scanned on a Shimadzu GCMS-QP2010 and the elemental analysis was obtained using a LECO CHNS-900 elemental analyzer (Lyon, France) and the values are within ±0.4% of the theoretical values.…”

“…As a result, a large number of 2-pyrazolines using different synthetic methods for their preparation have been described in the chemistry literature. An especially popular procedure is based on the reaction of α,β-unsaturated ketones with hydrazines [11][12][13]. The coupling of this chemical entity with a quinoline unit might be considered to have some biological activities.…”
