A reexamination of the sodium borohydride and palladium–charcoal reduction of 3-methyl-4-(o-nitrobenzylidene)-1-phenyl-2-pyrazolin-5-one (3a) has revealed that the final product is 3-methyl-4-(o-aminobenzyl)-1-phenyl-2-pyrazolin-5-one (5a), and not 9-hydroxy-3-methyl-3a,4,9,9a-tetrahydro-1H-pyrazolo[3,4-b]quinoline as claimed previously. Reduction of 3a to 5a proceeds via the 4-(o-nitrobenzyl) compound. Chemical and physical properties of 5a are described which support the assignment of this revised structure to the reduction product of 3a. Two analogs of 3a were also reduced in the same manner and yielded products analogous to 5a and not the previously claimed pyrazolo[3,4-b]quinolines.
