In order to synthesize the intermediates of cannabimimetics, the benzoylation of indoles with 2'/3'/4'-substituted benzoyl chloride in the presence of Et2AlCl was examined. Among the products, we found that the H-1 NMR spectra of 3-(2'-substituted)-benzoyl-2-methylindoles had interesting features. We investigated their physicochemical properties based on VT-NMR, and it was revealed that conformer A (s-trans) is present in preference to conformer B in these compounds.
