Procedure

8.0 g of N-methyl-(2-(3,4-dimethoxyphenyl)ethyl)amine was dissolved in 120 ml of N,N-dimethylformamide, followed by the addition of 6.8 g of anhydrous potassium carbonate and 14.4 ml of 1-bromo-3-chloro-2-methylpropane. The obtained mixture was reacted at a room temperature for 12 hours, followed by the addition of water. The obtained mixture was extracted with ethyl acetate. The ethyl acetate phase was washed with water and a saturated aqueous solution of common salt, dried over anhydrous potassium carbonate and distilled to remove the solvent. The obtained residue was purified by silica gel column chromatography [solvent: dichloromethane/methanol (50:1)] to obtain 4.67 g of the title compound as a pale yellow oil (yield: 40%).
