Versuchsvorschrift

A solution of 4-isopropylaniline (5.05 g, 37.3 mmol), methyl bromoacetate (5.99 g, 39.2 mmol) and anhydrous sodium acetate (3.21 g) in absolute methanol (30 mL) was heated to reflux for 2 h. The solution was cooled and poured into 300 mL water. The resulting solid was collected by filtration and recrystallized from ethanol/water to afford pure product, methyl-2-(4-isopropylanilino)acetate, m.p. 35-36° C. (4.53 g, 55%). 1H NMR (CDCl3, 300 MHz): δ7.06 (2H, d, J=8.2 Hz), 6.57 (2H, d, J=8.2 Hz), 4.18 (1H, v br), 3.90 (2H, s), 3.78 (3H, s), 2.81 (1H, m, J=7.0 Hz), 1.20 (6H, d, J=7.0 Hz). Mass spectrum (ES+): m/z 209 (3), 208 (31), 148 (100).
