実験手順
10 g (36 mmol) 4-(3-chloropropoxy)benzophenone was dissolved in 100 mL acetonitrile. 26.3 g (0.36 mol) n.-butyl amine was added and the mixture was heated to 70° C. for 30 hours. The solvent was evaporated under reduced pressure and the residue was treated with 500 mL water. The pH was adjusted to pH=1. The mixture was stirred for one hour at 40° C. The mixture was cooled to 10° C. and the precipitated compounds were isolated by filtration. The precipitate was treated with 200 mL water and the pH was adjusted to 12, using a 1 N NaOH-solution. The mixture was extracted with 200 mL methylene chloride. The organic fraction was dried over MgSO4 and evaporated under reduced pressure. The crude 4-[(3-butylamino)propoxy]benzophenone was purified by preparative column chromatography on a SVP D40 Merck-Np column, using a gradient elution from methylene chloride to methanol at a flow rate of 40 mL per minute. 4.4 g of 4-[(3-butylamino)propoxy]benzophenone was isolated.
