antiprotozoal

ChEBI: A benzamide obtained via formal condensation of 4-acetamidobenzoic acid and 2-(diethylamino)ethylamine.

1.0 g of p-amino-N-(2-diethylaminoethyl)benzamide is dissolved in chloroform. A few ice cubes are added to the solution. Acetyl chloride is added dropwise with stirring until no more white precipitate forms; the latter is separated by filtering under suction. The precipitate is washed with cold acetone and dried overnight in a vacuum oven at room temperature. The product is dissolved in a minimum amount of hot isopropanol and allowed to precipitate in the cold. The p-acetamido-N-(2-diethylaminoethyl)benzamide hydrochloride, is recrystallized a second time from hot isopropanol, melting point 190°-193°C. The free base is obtained from the hydrochloride by dissolving the latter in water, adjusting the pH to greater than 10 with dilute sodium hydroxide, and adding an equal volume of benzene. After shaking in a separatory funnel, the benzene layer is recovered and evaporated to dryness. So the p-acetamido-N- (2-diethylaminoethyl)benzamide is obtained.

Antiarrhythmic

The relaxant effects of N-acetylprocainamide on bovine tracheal smooth muscle was studied.
