Reaktionsschritte

To a mixture of 4.9 g (47 mmol) of thiocarbohydrazide and 15 g (47 mmol) of 4-(dodecylsulfonyl)butanoic acid in 30 ml of toluene was added 0.8 g (4.7 mmol) of 3-nitrobenzeneboronic acid. The mixture was heated at reflux for 24 hr. Upon cooling, the thick precipitate was collected, rinsed with a small amount of acetonitrile (10 ml), dried in vacuo to yield 16 g (87.4%) of the desired product as a white solid. All of the analytical data confirmed the assigned structure.
