Source of material
The title compound was prepared by the following method: N′-benzylidene-4-methylbenzenesulfonohydrazide (0.823 g, 3 mmol) and NaOMe (0.243 g, 4.5 mol) in anhydrous methanol 20 mL were mixed. The reaction mixture was refluxed for 24 h in 323 K, then washed in portions with water and extracted by dichloromethane. The organic layer was evaporated and purified by column chromatography using ethyl acetate and petroleum ether. Crystallization from ethyl acetate/petroleum ether gives a colorless solid; Yield 81%.
Experimental details
All hydrogen atoms were placed geometrically on calculated positions using a riding model with the help of the SHELX program [2].
Discussion
Tosylhydrazones have versatile applications converting into various pharmaceutical and biological medicine [3], [4], [5], [6], [7]. It is well known that tosylhydrazones transform into diazo compounds under basic environment via a Bamford-Stevens reaction [8]. In addition, N-alkylation of tosylhydrazones via a metal-free reductive coupling procedure, are reported [9] while palladium catalysts are used in previous cases [10]. The product of the N-alkylation of tosylhydrazones are important synthetic intermediates as well [11, 12] .
The geometry and labeling for the crystal structure of the title complex is depicted in the figure. Geometric parameters are in the expected ranges.
