1-(2-氯乙氧基)-2-乙氧基苯

反应条件: temp:110.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: A mixture of 2 g of N-[4-ethoxy-4-(4-fluorophenyl)butyl]amine, 2 g of 2-(2-ethoxyphenoxy)ethyl chloride, 0.1 g of sodium iodide, 1 g of sodium bicarbonate and 20 ml of N,N-dimethylformamide was stirred at about 110° C for 20 hours. After cooling, the reaction mixture was poured into 200 ml of water and extracted with benzene. The benzene layer was washed with water, dried over anhydrous sodium sulfate and concentrated under reduced pressure. The residue was treated with ethanolic oxalic acid and recrystallized from ethanol to give N-[4-ethoxy-4-(4-fluorophenyl)butyl]-2-(2-ethoxyphenoxy)ethylamine oxalate, M.P. 157° - 160° C. After cooling extracted with benzene The benzene layer was washed with water dried over anhydrous sodium sulfate concentrated under reduced pressure The residue was treated with ethanolic oxalic acid recrystallized from ethanol
