Versuchsvorschrift

7.4 g of dimethylaminomethylene-glutacononitrile, 100 ml of DMF and 4.4 g of 35.6% strength aqueous methylamine solution were held for 2 hours at 80° C. in an 0.3 l V4A autoclave. After the mixture had been removed and concentrated, 6.4 g of 2-methylamino-5-cyanopyridine (purity 93%) were obtained, which corresponds to 90.2% of theory.
