Versuchsvorschrift

In a 250 ml flask 4-(2-fluoro-5-bromobenzyloxy)but-2-enyl bromide (1.968 g, 5.89 mmol) was dissolved in dry tetrahydrofuran (40 5 ml). To this solution methylamine (29.5 ml, 58.9 mmol) was added in one portion and the resulting mixture was stirred at ambient temperature for five hours. The progress of the reaciton was monitored by thin layer chromatography. The solvents were removed in vacuo and the residue was taken up in 1 M potassium carbonate and extracted thrice with methylene chloride. The organic fractions were combined, and dried over sodium sulfate. The solvents were removed in vacuo. The desired title intermediate was further purified by liquid chromatography.
