Answer 2

To synthesize benzanilide from benzoic acid, the carboxylic acid group of benzoic acid needs to be converted into an amide group. This can be achieved through a reaction with aniline using a dehydrating agent such as thionyl chloride or phosphorus trichloride. The reaction usually takes place at an elevated temperature under reflux conditions, yielding benzanilide and hydrogen chloride as byproduct. Purification of the crude product can be done through recrystallization in a suitable solvent.
