2-Cyano-5-({4-[N-methyl-N-(2-hydroxyethyl)amino] phenyl}diazenyl)pyridine
In the title compound, C(15)H(15)N(5)O, the benzene and pyridine rings make a dihedral angle of 30.86 (7)°. In the crystal, chains of mol-ecules are wrapped around the screw axes into compressed helices, through hydrogen bonding between the hy-droxy and cyano groups. The chains are linked by weak C-H⋯N and C-H⋯O inter-actions. The π conjugated unit of the mol-ecule is almost perpendicular to th...
متن کاملMethyl 4-amino-2-chloropyrimidine-5-carboxylate
In the title compound, C6H6ClN3O2, all non-H atoms are approximately coplanar [maximum deviation = 0.012 (4) Å]; an intra-molecular N-H⋯O hydrogen bond occurs between the amino group and the carbonyl group. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into supra-molecular chains propagated along [101].
متن کامل(E)-4-Methyl-2-{[tris(hydroxymethyl)methyl]iminiomethyl}phenolate
In the zwitterionic title compound, C(12)H(17)NO(4), an intra-molecular N-H⋯O hydrogen bond generates a six-membered ring, producing an S(6) ring. In the crystal structure, mol-ecules are linked by inter-molecular C-H⋯O and O-H⋯O inter-actions.
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 کامل6-Amino-3-methyl-4-(4-nitrophenyl)-1-phenylpyrazolo[3,4-b]pyridine-5-carbonitrile
The title compound, C(20)H(14)N(6)O(2), contains four rings. The dihedral angle between the pyridine ring and the pyrazole ring is 1.9 (1)°, i.e. almost coplanar, which gives rise to a conjugated structure. The dihedral angle between the nitro-substituted phenyl ring and the pyridine ring is 76.3 (1)° and that between the pyrazole ring and the non-substituted phenyl ring is 40.5 (1)°. In the cr...
