3‐Ethyl 1‐methyl pyrrolo[2,1‐a]isoquinoline‐1,3‐dicarboxylate
TL;DR: In this article, the pyrrolo[2,1-a]isoquinoline unit is planar and the crystal structure is stabilized by weak intra-and inter-molecular C-H⋯O inter-actions, and also by π-π inter-action with centroid-centroid distances of 3.5680-3.6683
