Versuchsvorschrift

3-n-Propyl-aniline (20 g, 148 mmol), sodium bicarbonate (24.9 g, 296 mmol) and methyl chloroacetate (24.0 g, 221 mmol) were mixed under nitrogen and stirred at 80°-90° C. for 24 h. The cooled reaction was poured into ether (100 ml) and filtered. The filtrate was washed with water (100 ml), dilute hydrochloric acid (100 ml) and water (100 ml), then dried and concentrated in vacuo. The oily product (21.2 g) was distilled on the Kugelrohr collecting the fraction boiling at 160°/0.35 mmHg to give the title compound (Intermediate 32) as a colourless liquid which solidified into a pale yellow, low melting solid (16.1 g, 53%).
