0.138 g (1 mmole) of 1,2-dimethoxybenzene (veratrol) were reacted with 0.223 g (1 mmole) of bromomethyl octylether in 5 ml 1,2-dichloroethane in the presence of 0.12 ml (1 mmole) SnCl4 at room temperature for 1 hour. After washing with HCl and water, followed by drying on Na2SO4 the product was isolated by the evaporation of the solvent. The product (0.275 g) corresponds by mp., NMR and analysis to cyclotriveratrylene (A. J. Lindsey. J. Chem. Soc. 1685 (1965) obtained by trimerization of 3-chloromethyl-1,2-dimethoxybenzene.
