Abstract
The 2-(.omega.-alkylaminoalkyl)- and 2-(.omega.-dialkylaminoalkyl)-3-(4-X-benzylidene)phthalimidines are useful as local anesthetics. For the preparation, the adduct is formed between the suitable 3-(4-X-benzylidene)phthalide and a substituted amino-alkylamine, the adduct being then reacted with acetic anhydride; the X substituent at the position 4 of the benzylidene group then can be suitably converted according to the requirements.
