A series of fluoro-substituted imipramines and its analogues, 6a-6e, were synthesized and evaluated for their in vitro localanestheticactivity. Compound 6b was found to have potency, onset, and duration of action comparable to those of lidocaine (lidocaine hydrochloride, CAS:6108-05-0). Dissociation constants (pK(a)) of these compounds have been determined to be 7.6-7.9.
