The reaction between benzyne and the Schiff bases 1a,b and 15a,b leads to the 1,4-bis(2-substituted acridin-10-yl)benzene 4a,b, the N- phenylarylamines 10a,b and the 10-(4-formylphenyl)-substituted acridines 11a,b (from 1a,b) and the 2-substituted acridine-10-carboxyaldehyde 18a,b (from 15a,b). Cyclohexyl (4-cyclohexyliminomethylbenzylidine)amine 1c reacts with benzyne by an ene-reaction to give cyclohexenyl[(4- cyclohexyliminomethylphenyl)benzylidine]amine 14.

The synthesis of 2-methyl-5H-dibenz[b,f]azepine-5-carboxamide (2-methylcarbamazepine, 2-MCBZ), a promising internal standard for chromatographic assays of the antiepileptic agent carbamazepine is described. N-(p-tolyl)anthranilic acid was utilized as a starting material for the synthesis of a key compound, 2,9-dimethylacridine, which was converted in two steps to 2-methyl-9-hydroxymethylacridan. The acridan, in the presence of polyphosphoric acid, was ring-expanded to form 2-methyl-5H-dibenz[b,f]azepine, this latter compound being converted by conventional reactions to its 5-carbamyl derivative, 2-MCBZ.
