3-苯基丁酰基 氯化物

反应条件: temp:10.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To the solution of phenol (8.62 g, 92 mmol) and 4-dimethylaminopyridine (400 mg) in toluene (110 ml) was added pyridine (18.1 g, 229 mmol) and the resulting solution was cooled to 10° C. Then a solution of 3-phenylbutanoyl chloride (20.1 g, 110 mmol) was added dropwise. The resulting mixture was stirred at room temperature for 24 h, and then cooled to 5° C. before the careful addition of 2N aq. HCl-solution (225 ml). The mixture was stirred intensely for 15 min, then diluted with toluene and transferred into a separatory funnel. The aqueous layer was separated and the organic layer washed 4 times with water, then brine and dried over MgSO4. The solvent was removed in a rotary evaporator and the residue short-path distilled at 125-128° C./0.07 mbar to yield 18.52 g (70%) of colourless oil. The mixture was stirred intensely for 15 min transferred into a separatory funnel The aqueous layer was separated the organic layer washed 4 times with water brine and dried over MgSO4 The solvent was removed in a rotary evaporator the residue short-path distilled at 125-128° C./0.07 mbar
