Reaction Steps

Sixty-three and one half grams of m-amino pentafluoropropionanilide is dissolved in 150 ml of tetrahydrofuran containing 65 g. of triethylamine. This mixture is added dropwise with cooling to 37 g. of phosgene dissolved in 150 ml of tetrahydrofuran cooled to -5° C. When addition is complete the mixture is allowed to warm up to room temperature. The triethylamine hydrochloride is filtered off and the solvent is removed under vacuum. The product, 70 g., was not isolated but diluted to 140 ml with tetrahydrofuran and used in subsequent reactions.
