Reaction Steps

A mixture of 4-fluoro-2-nitrobenzaldehyde (8.70 g., 51.5 millimoles), 2-cyanoacetamide (4.7 g., 54.4 millimoles), piperidine (0.032 g., 0.37 millimole) and ethanol (80 ml.) is stirred at room temperature for 28 hours. The solid which formed is separated by filtration, washed with ethanol (45 ml.) and dried. Yield = 10 g. (83.5%) of the title acrylamide as light tan crystals. M.P. 278°-279° C.
