Source of material
A suspension of 5-methoxy-1H-indole-2-carboxylic acid (2 g, 0.01 mol) in absolute methanol (30 mL) and a few drops of concentrated sulfuric acid was heated to reflux for 4 h. The reaction mixture was allowed to cool to room temperature and the precipitated solid was filtered off to give 2.1 g (96%) of methyl 5-methoxy 1H-indole-2-carboxylate as yellow crystals m.p. 450–451 K [1]. Single crystals of the title compound were obtained via slow evaporation of methanolic solution.
Discussion
The pineal hormone melatonin (N-acetyl-5-methoxytryptamine, MLT) is primarily synthesized and released by the pineal gland in a circadian rhythm, with elevated peripheral blood levels at night. MLT appears to have sleep-inducing properties in addition to the other effects reported in the literature like anti-inflammatory, pain modulatory, antitumor and antioxidant properties [2–5]. MLT exerts its effects via manipulation of two G-protein-coupled receptors, namely MT1 and MT2 receptors as well as a low-affinity putative MLT binding site called MT3 [6, 7]. The title compound is the starting material of a number of melatoninergic ligands [8] and can serve as a starting synthon for other new compounds able to modulate melatonin receptors. The asymmetric unit of the title structure contains one complete molecule in which the indole moiety is nearly planar. The stability of the molecules in the crystal structure is ensured by one intermolecular hydrogen bond, of which O1 works as hydrogen bond acceptor and N1 works as hydrogen bond donor. The distance of the interactions between N1—H1⋯O1 is 2.03(1) Å and the angle is 160°.
