2-[3-Cyano-4-(2-methylpropoxy)phenyl]-4-methylthiazole-5-carboxylic acid pyridine solvate
In the title compound, C(16)H(16)N(2)O(3)S·C(5)H(5)N, the benzene and thia-zole rings of the Febuxostat [2-(3-cyano-4-isobut-yloxy)phenyl-4-methyl-5-thia-zolecarboxylic acid] mol-ecule are almost coplanar [dihedral angle = 2.4 (1)°]. The carboxyl group is coplanar with the thia-zole ring [O-C-C-C and O-C-C-S torsion angles of -0.7 (4) and 0.6 (3)°, respectively]. The pyridine mol-ecule of cryst...

The title compound, C12H12BrNO4S2, was obtained by the Sandmeyer reaction from ethyl 3-amino-4-cyano-5-[(2-eth-oxy-2-oxoeth-yl)sulfan-yl]thio-phene-2-carboxyl-ate. The dihedral angle between the thiophene ring and linked CO2 ester group is 2.0 (5)°.
متن کاملTriphenylphosphine Catalysed Facile Multicomponent Synthesis of 2-Amino-3-Cyano-6-Methyl-4-Aryl-4H-Pyrans
Triphenyl phosphine(PPh3), an efficient and reusable catalyst, catalysed the synthesis of 2-amino-3-cyano-6-methyl-4-aryl-4H-pyran-5-ethylcarboxylate derivatives by one-pot condensation of aromatic aldehydes, malononitrile and ethyl acetoacetate in EtOH-H2O (1:1) at reflux conditions. The results show that ...
متن کامل2-Chloro-N-[1-(4-chlorophenyl)-3-cyano-1H-pyrazol-5-yl]acetamide
The title compound, C(12)H(8)Cl(2)N(4)O, was synthesized by the reaction of 5-amino-1-(4-chloro-phen-yl)-1H-pyrazole-3-carbonitrile and 2-chloro-acetyl chloride. The dihedral angle between the pyrazole and benzene rings is 30.7 (3)°. In the crystal structure, strong N-H⋯O hydrogen bonds link the mol-ecules into chains along [001]. C-H⋯N hydrogen bonds are also present.
