Figure 2
The crystal packing of 4-benzyl­oxyindole (1) along the a axis (top left), N-2-propyl-α-oxo-4-(phenyl­meth­oxy)-1H-indole-3-acetamide (2) along the b axis (top right), 4-benz­yloxy-N-iso­propyl­ammonium chloride (3a) along the a axis (bottom left), and 4-hy­droxy-N-iso­propyl­tryptamine (4) along the a axis (bottom right). The hydrogen bonds (Tables 2[link]–4[link][link]) are shown as dashed lines. Hydrogen atoms not involved in hydrogen bonds are omitted for clarity.
