Reaktionsschritte

7.5 g of nicotinoyl-acetone are dissolved in 45 ml of anhydrous ethanol and, after adding 20 ml of ammonia, the mixture is then stirred for 3 days at 50° C in an autoclave. Concentrating the clear solution leaves an oil which becomes solid after a short time. After recrystallisation from toluene, 2-nicotinoyl-1-methylvinylamine (melting point 82°) is obtained in a 91% yield.
