Abstract N-(2-Chloro-5-cyanophenyl)-4,4,4-trifluorobutanamide (3) was synthesized by reacting 4,4,4-trifluorobutanoic acid (1) with 2-amino-4-chlorobenzonitrile (2) in the presence of triethylamine and propylphosphonic anhydride in ethyl acetate. Character­ization of the compound was done by IR, 1H-NMR, 13C-NMR, LC-MS and CHN analysis. Full article

The indole ring system is a prominent partial structure of several protein kinase inhibitor families. The title compound is the first example of a 5-substituted indolyl squaryl chloride with free indole nitrogen. It has been synthesized by reaction of 5-methoxyindole with squaric acid dichloride in diethyl ether and its IR, 1H-NMR, 13C-NMR, MS, UV and HPLC data are presented. This compound may prove to be a rather useful building block for the preparation of various derivatives for biological studies. Full article

Abstract
As a consequence of one-pot, three-component reaction of trans-2-benzoyl-3-(4-nitrophenyl)aziridine with 5-chloro-3-methyl-1-phenyl-1H-pyrazole-4-carbaldehyde and ammonium acetate, 2-(5-chloro-3-methyl-1-phenyl-1H-pyrazol-4-yl)-6-(4-nitrophenyl)-4-phenyl-1,3-diazabicyclo[3.1.0]hex-3-ene was achieved in good yield. The desired photochromic compound display interesting photochromic behavior in the crystalline and solution phase. The structure of the
