Versuchsvorschrift

To a cold solution consisting of phenethylamine (20g,0.16mol) in tetrahydrofuran (900 mL) was added triethylamine (23 mL, 0.16 mol). To this solution was added dropwise chloromethylformate (64 mL, 0.8 mol). The reaction mixture was then stirred overnight water (450 mL) was added and the layers were separated. The organic layer was washed successively with water (1×200mL) and brine (1×200mL). The organic solvent was dried (anhydrous magnesium sulfate), filtered and concentrated to give the title compound (28 g, 94% yield).
