Versuchsvorschrift
To a solution of 1-ethylpiperidine (2.5 g, 22.1 mmol) in dichloromethane (4 mL) was added ethylbromoacetate (3.7 g, 22.1 mmol) via a syringe. The mixture was stirred at room temperature overnight. The resulting white precipitate was washed with hexane and ethylacetate to give 6.1 g, 98.6% yield of the product as a white solid. Positive mode ESI/MS: m/z=200.4 (M+, minus Br); confirmed by 1H NMR.
