چکیده
The title compound, C(26)H(27)N, was prepared by the elimination of water from N-(2,6-diisopropyl-phen-yl)-2,2-diphenyl-acetamide. The angle at the central C atom of the cumulene measures 172.5 (4)°. Mol-ecules are connected into infinite chains by inter-molecular C-H⋯N inter-actions.

The mol-ecular conformation of the title compound, C(26)H(30)N(2), is reinforced by an intra-molecular N-H⋯N hydrogen bond, resulting in an almost planar [mean deviation of 0.023 (2) Å] S(6) ring. The dihedral angles between the central benzene ring and the terminal unsubstituted and substituted aromatic rings are 64.45 (9) and 89.40 (8)°, respectively.

متن کاملOne-pot and one-step novel N-methylation of 2,6-diaminopyridine
2,6-diaminopyridine is extensively used as a pharmaceutical intermediate and a hair dye coupler as oxidation formulations. It is soluble in protic solvents. Primary and secondary amines are N-methylated by various methods such as direct alkylation of amines with Hofmann mechanism, but in many of these methods due to overalkylations, we earn a mixture of amino products. Consequently, they aren't...
