Reaction Steps

To 0.5 g (3.4 mmol) (2) in 10 ml isopropanol was added 0.39 g (3.4 mmol) methyl 3-aminocrotonate and 0.39 g (3.4 mmol) methyl acetoacetate and the resulting solution refluxed overnight. The cooled reaction mixture was then diluted with 15 ml ether and stirred for 1 hour. The tan solid was filtered off and recrystallized from ethyl acetate to give pure (3), m.p. 202°-205° (dec).
