The mol-ecule of the title compound, C(12)H(14)N(4), lies about a crystallographic inversion centre. The five- and six-membered rings are twisted from each other, forming a dihedral angle of 18.06 (7)°. In the crystal structure, neighbouring mol-ecules are linked by inter-molecular N-H⋯N hydrogen bonds into one-dimensional infinite chains forming 18-membered rings with R(2) (2)(18) motifs. The ...
The chemical name of the title compound in the paper by Kia, Fun & Kargar [Acta Cryst. (2009), E64, o2406] is corrected.[This corrects the article DOI: 10.1107/S1600536809023320.].
n-(7-chloro-1-methyl-2-oxo-5-phenyl-2,3-dihydro-1h-benzo[e][1,4]diazepin-3-yl)thiophene-2 carboxamide-[14c-carboxy] was prepared as part of a 6-step sequence from thiophene-2-carbonitrile -[cyano-14c] as a keysynthetic intermediate which has been synthesized from 2-iodothiophene and zinc [14c]-cyanide in thepresence of tetrakis (triphenylphosphine) palladium.
In order to investigate the effects of dimethylamino substituent at postion 2 of the dihydropyridine nucleus on its activity, dialkyl 1,4-dihydro-2-[2-(dimethy- lamino) ethyl]-6-methyl-4-(1-benzyl-2-alkylthio-5-imidazolyl)-3,5-pyrdinedicar- boxylates (6a-f) were synthesized. The synthesis was started from dialkyl 1,4- dihydro-2,6-dimethyl-4-(1-benzyl-2-alkylthio-5-imidazolyl)-3,5-pyridine...
In order to investigate the effects of dimethylamino substituent at position 2 of the dihydropyridine nucleus on activity, starting from dialkyl l ,4-dihydro-2,6-dimethyl-4- (l-benzyl-2-alkylthio-5-imidazolyl)-3,5-pyridinedicarboxylates (5a-f) which their synthesis and effects as calcium channel antagonist on guinea-pig ileum has been reported previously, dialkyl l,4-dihydro-2-[2-(dimethyla...
In this work, series of new chalcones derived from indole compounds were synthesized. the first compound 2-(1,1-dimethyl-1,3-dihydro-2H-benzo[e]indol-2-ylidene)malonaldehyde was synthesized reaction 1,1,2-trimethyl-1H-benzo[e]indole with Phosphoryl chloride in presence (DMF). Schiff base (C2) prepared by 2-(1,1-dimethyl-1,3-dihydro-2H-benzo[e]indol-2-ylidene) malonaldehyde 3-amino acetophenone ...
