Versuchsvorschrift

2,5-Dimethylphenylacetyl chloride (2.1 g, 11.5 mmol) was added dropwise to a mixture of 2-amino-3-(1-methoxy-piperidin-4-yl)-propionic acid methyl ester (1.7 g, 7.8 mmol) and K2CO3 (2.1 g, 15.2 mmol) in 50 mL of THF at room temperature. After the addition, the mixture was stirred for 0.5 h and diluted with 50 ml of water. The mixture was extracted with EtOAc five times and the combined organic layers were dried over sodium sulfate, filtered and concentrated under vacuum. The residue was purified by column chromatography on silica gel. Yield: 1.2 g of 2-[2-(2,5-dimethyl-phenyl)-acetylamino]-3-(1-methoxy-piperidin-4-yl)-propionic acid methyl ester as a solid.
