Condensation of 3-(4-fluorophenyl)-1H-pyrazole-4-carbaldehyde with 2-naphthyl- or 6-quinolylamine and CH-acids (acetone, acetophenone, cyclic mono- and beta-diketones) provided new derivatives of benzo[f]quinoline, benzo[a]phenanthridine, benzo[a]acridine, and 4,7-phenanthioline. The arising in the course of the reaction [3-(4-fluorophenyl)-1H-pyrazole-4-ylmethylene]-2-naphthyl-(or 6-quinolyl)amines, [3-(4-fluorophenyl)-1H-pyrazole-4-ylmethylene]-1,3-indandione, and octahydro-1,8-xanthenedione derivatives were isolated.
