Procedure
10 g (55.05 mmol) tert.-butyl β-alaninate hydrochloride are dissolved in 50 ml tetrahydrofuran, and 11.14 g (110.1 mmol) triethylamine and 5.53 g (36.7 mmol) ethyl 3-chloro-3-oxopropanoate are added at 0° C. The reaction mixture is stirred at room temperature for 18 hours. The solvent is removed in vacuo and the product is isolated by column chromatography (silica, eluent dichloromethane/methanol 100:1→50:1).
