2-(5,6-Diphenyl-1,2,4-triazin-3-yl)aniline
The title compound, C21H16N4, obtained under standard Suzuki cross-coupling conditions, is a model compound in the synthesis and biological activity evaluation of new aza-analogues of sildenafil containing a pyrazolo-[4,3-e][1,2,4]triazine system. An N-H⋯N intra-molecular hydrogen bond involving the amino-benzene system and the 1,2,4-triazine moiety helps to establish a near coplanar orientatio...

The title compound, C(19)H(17)ClN(4), was obtained from the reaction of 3-chloro-5,6-diphenyl-1,2,4-triazine with isobutyronitrile in the presence of lithium diisopropyl-amide as an unexpected product of covalent addition of isobutyronitrile carbanion to the C-5 atom of the 1,2,4-triazine ring. The 2,5-dihydro-1,2,4-triazine ring is essentially planar (r.m.s. deviation = 0.0059 Å) and the 5- an...
متن کاملCrystal structure of 3-amino-1,2,4-triazin-5(2H)-one.
because of various interesting biological activities.1 The tautomeric proton is highly effective at making strong intermolecular hydrogen binding with other heteroatoms of molecules involved with biological activity. The title compound 3-amino-1,2,4-triazin-5(2H)-one (6-azaisocytosine, Fig. 1), an isosteric isomer of isocytosine, can exist in several tautomeric forms, which have been discussed ...
متن کامل4-(2-{[4-Amino-6-(4-nitrobenzyl)-5-oxo-4,5-dihydro-1,2,4-triazin-3-yl]sulfanyl}acetyl)-3-phenylsydnone
In the crystal, C(20)H(15)N(7)O(6)S, the dihedral angle between the oxadiazole and triazine rings is 86.94 (7)°. The oxadiazole ring makes a dihedral angle of 52.96 (8)° with the phenyl ring, while the triazine ring makes a dihedral angle of 82.08 (7)° with the benzene ring. In the structure, mol-ecules are linked by a pair of N-H⋯O hydrogen bonds, forming an inversion dimer. The dimers are fur...
متن کاملThe Reactions of 3- Mercapto-6-Methyl- 1,2,4- Triazin-5(2H)-one with Alkyl Phosphites
The reaction of 3-mercapto-6-methyl-1, 2, 4-triazin-5 (2H)-one 1 with dimethyl 2a and trimethyl phosphite 3a at 100 C in absence of solvent yields the dimeric product 4 and while the alkylated products 5 and 6 are obtained for reaction with 3a. Methylation of 1 by methyl iodide gives alkylated product 5. Reaction of 1 with diethyl 2b and triethyl phosphite 3b by the same previous conditions yie...
