Versuchsvorschrift
The preparation of N-[2-(cyclopent-2-enyl)phenyl]-N-(2-methoxyethyl)-2-chloroacetamide was conducted in a fashion analogous to example 2. Reaction of 30.00 g (188.4 mmol) of 2-(cyclopent-2-enyl)aniline, 75.75 g (750 mmol}of triethylamine, and 70.91 g (750 mmol) of 2-chloroethyl methyl ether at 100° C. in a closed, 500 mL flask for 56 hr. afforded ca. 40 g of a crude product consisting of, in part, 90.05 wt % of N-(2-methoxyethyl)-2-(cyclopent-2-enyl)aniline and 7.24 wt % of 2-(cyclopent-2-enyl)aniline. Acylation of this material with 2-chloroacetyl chloride provided ca. 50 g of a product consisting of, in part, 89.35 wt % of N-[2- cyclopent-2-enyl)phenyl]-N-(2-methoxyethyl)-2-chloroacetamide and 8.84 wt % of N-[2-(cyclopent-2-enyl)phenyl]-2-chloroacetamide. This material was purified by column chromatograph then bulb-to-bulb distillation (bp 165-175°C/1 mm/Hg).
