Cyanoacetamide (19.4 g., 0.23 mole) is added to a solution of sodium ethoxide (6.65 g., 0.29 mole) in absolute ethanol (460 ml.) maintained at 50° C. The mixture is stirred and o-aminobenzaldehyde (28.0 g., 0.23 mole) in absolute ethanol (100 ml.) added. After fifteen minutes stirring at 50° C., the reaction mixture is cooled in an ice bath, filtered and dried to give 34.5 g. (84% yield) of product; m.p. 240°-242° C.
