실험 절차

A solution of 3-bromopropanol (53.86 g, 0.368 mol) in isopropanol is added dropwise to a mixture of 2,4-dichlorophenol (50 g, 0.307 mol) and 1,8-diazabicyclo[5.4.0]undec-7-ene (70.05 g, 0.406 mol) in isopropanol at reflux. The reaction mixture is heated at reflux for 3 hours and concentrated in vacuo to obtain a residue. The residue is dissolved in methylene chloride and the organic solution is washed sequentially with 0.5N sodium hydroxide solution, 1M hydrochloric acid and brine, dried over MgSO4 and concentrated in vacuo to obtain an oil which solidifies to give the title product as a white solid (71.9 g, mp 53°-55° C.).
