참여 물질

반응 단계

32.27 g of homopiperazine, 13.2 g of 2-(3,4-dimethoxyphenyl)ethyl chloride and 71.3 g of potassium carbonate were added to 500 ml of acetonitrile. The obtained mixture was heated under reflux for 20 hours, cooled and filtered. The filtrate was concentrated under a reduced pressure to obtain a residue. This residue was extracted with ether thrice. The extracts were combined, dried over anhydrous sodium sulfate and filtered. The filtrate was concentrated under a reduced pressure. The obtained residue was purified by silica gel column chromatography (solvent: chloroform/methanol/isopropylamine (100:10:1)) to obtain 13.40 g of the title compound as a yellow oil (yield: 77%).
