Versuchsvorschrift
5 g (30.74 mmol, 1 eq) of octanoyl chloride and 3.58 g (33.81 mmol, 1.1 eq) of 4-methyl-3-thiosemicarbazide in solution in 350 ml of tetrahydrofuran are stirred for 3 hours at room temperature. The solution is concentrated to dryness. The solid obtained is taken up in 350 ml of a 10% aqueous potassium hydroxide solution 35 g (0.82 mmol, 20 eq). The reaction mixture is stirred overnight under reflux. In the cold state, the reaction medium is acidified. The precipitate obtained is filtered, washed with a minimum of water and then dried. 5.94 g (90%) of the expected compound are obtained.
