Versuchsvorschrift

To a stirred solution of cyanothioacetamide (2.20 g, 22 mmol) and 6-methyl-2,4-heptanedione (3.12 g, 22 mmol) in anhydrous EtOH (40 mL) was added triethylamine (0.4 mL) and the reaction was heated at 50° C. for 1 h before it was allowed to cool to room temperature. Filtration and washing of the precipitates with EtOH gave 6-isobutyl-2-mercapto-4-methylnicotinonitrile as a yellow solid (2.8 g, 61%).
