Toluene → 1-Bromo-12-(4-phenylpiperazinyl)dodecane

関与物質

反応手順

A mixture of 6.56 g of 1,12-dibromododecane, 3.24 g of N-phenylpiperazine, 2.53 g of triethylamine, and 50 ml of toluene was heated under reflux for 2 hours. To the reaction mixture was added 100 ml of ethyl acetate, and the mixture was washed successively with water and a saturated sodium chloride aqueous solution, and dried over magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was subjected to column chromatography using a 1:2 mixture of ethyl acetate and hexane as a developing solvent to yield 4.1 g of 1-bromo-12-(4-phenylpiperazinyl)dodecane (m.p.=26.0°-28.0° C.).
