Versuchsvorschrift

To a solution of 2.541 g (12.441 mM) of 5-thia-1,8b-diazaacenaphthylene-4-methanol in 30 ml of N,N-dimethylformamide was added 6 g of activated manganese dioxide (Aldrich), and the mixture was stirred at room temperature overnight. This reaction mixture was filtered and the filter cake was washed with N,N-dimethylformamide. The filtrate and washes were combined and the solvent was distilled off under reduced pressure. The crude 5-thia-1,8b-diazaacenaphthylene-4-carbaldehyde thus obtained was not purified but used as it was in the next reaction.
