4-Methyl-N-[2-(2-phenyl-ethyn-yl)phen-yl]-N-(prop-2-yn-1-yl)benzene-1-sulfonamide

The title compound, C(24)H(19)NO(2)S, was prepared by propargylation of the sulfonamide. The tolyl group points to the planar tolane unit. In the extended structure, two inter-molecular hydrogen bridges connect the mol-ecules to form chains.
