Versuchsvorschrift

A stirred mixture of cyanoacetamide (84 g.), triethylorthoacetate (178 g.) and morpholine (108 g.) was heated under reflux for 3 hours. The initial reflux temperature was 104° C. and the final reflux temperature was 89° C. At the end of the reflux period acetonitrile (50 ml.) was added, the mixture was cooled at 25° C., the crystalline precipitate was collected, and washed with 2 × 100 ml. of cold ethanol. Weight = 104.7 g. Yield = 53%. A sample was recrystallized from ethanol as white needles m.p. 173°-174.5° C.
