Versuchsvorschrift

To O-benzyl-N-(tert-butoxycarbonyl)homoserine (5.8 g, 18.9 mmol) in 20% methanol/benzene (72 mL) is added 2M trimethylsilyldiazomethane in hexane (12.3 mL, 24.5 mmol), and the reaction stirred at room temperature 1.5 h. The solution is concentrated under reduced pressure to give the title compound in pure form. ESI MS m/z 324.2 [M+H]+.
