Versuchsvorschrift

To a solution of 2-nitro-4-trifluoromethyl-benzonitrile (71.7 g, 318.5 mmol) in anhydrous ethanol (400 mL) at room temperature was added sodium ethoxide (238 mL, 637 mmol, 21% solution in ethanol) dropwise over a period of 30 min. The reaction mixture was stirred at room temperature for 1 h. Water (1 L) was added, and the mixture was stirred for 15 min. The solids were filtered off, washed with water, and dried in the vacuum oven (40° C.) overnight to give 2-ethoxy-4-trifluoromethyl-benzonitrile (64 g, 93% yield).
