Reaction Steps

A solution of 10.00 g (62.8 mmol) of 2-(cyclopent-2-enyl)aniline from Example 1 in 150 mL of methylene chloride and 5.28 g (62.8 mmol) of sodium bicarbonate in 15 mL of water were combined with rapid stirring and cooled 0° C. with the aid of an ice bath. A solution of 7.099 (62.8 mmol) of chloroacetyl chloride in 25 mL of methylene chloride was then added dropwise through the course of 20 min. After an additional hour of vigorous stirring. the layers were separated and the organic layer was dried over anhydrous magnesium sulfate. Evaporation of the solvent in the organic layer and recrystallization of the precipitate with ether afforded 11.41 g (77% yield) of N-[2-(cyclopent-2-enyl)phenyl]-2-chloroacetamide: mp 101°-102° C.
