How might the structure of benzocaine be modified to create a compound having greater anesthetic properties?

Question

Quizplus · Accepted Answer

Extending the ester group away from the benzene ring and adding an additional nitrogen atom would increase the anesthetic properties of benzocaine. The addition of the nitrogen would increase the basicity of the molecule, allowing it to interact more effectively with the ion channels involved in anesthesia. Extending the ester group can improve the lipophilicity of the molecule, which can increase its efficacy as a topical anesthetic. The other options (A, B, and D) may alter the structure of the molecule, but they are unlikely to enhance its anesthetic effects.
