A nonlinear 1D chain with nonlocal interaction is considered. Using the multiscale expansion method, a nonlocal equation is obtained that describes the propagation of envelope waves in a medium.The properties of the obtained equation were studied and exact soliton-like solutions were constructed by the Darboux method of transformations.
