Versuchsvorschrift

To 110 ml of a 2M solution of ethyl amine in tetrahydrofuran (THF) at 0° C. was added dropwise ethyl acrylate (8.0 ml, 73.92 mmol) in 40 ml of tetrahydrofuran (THF). The reaction mixture was stirred overnight at room temperature. The reaction solution was filtered through a cotton wool plug and concentrated under reduced pressure to yield the title compound 10 (9.01 g, 84%) as a clear liquid. υmax/cm−1 3319.68, 2969.10, 1732.07, 1191.87 (FT-IR: FIG. 8)
