Versuchsvorschrift
A 10% solution of ethyl 2-cyano-2-ethyl-2-phenylacetate in ethanol is saturated with ammonia under cooling. The reaction mixture is allowed to stand at 5° C. for 96 hours, thereafter the solvent and the excess of ammonia are removed, and the product is filtered off. 2-Cyano-2-ethyl-2-phenylacetic acid amide is obtained with a yield of 80%; m.p.: 116.5°-117° C.
