2-cyano-N-(2-ethylphenyl)acetamide

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: As for Example 1, 2-cyano-2'-ethylacetanilide is heated with N,N-dimethylacetamide dimethylacetal to give 2-cyano-3-dimethylamino-2'-ethylcrotonanilide as colorless prisms, m.p. 79°-81.5° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: As for Example 1, 2-cyano-2'-ethylacetanilide as long needles, m.p. 128°-130° C. (prepared by the procedure described in U.S. Pat. No. 3,116,312), is heated with N,N-dimethylformamide dimethylacetal to yield 2-cyano-3-dimethylamino-2'-ethylacrylanilide as colorless prisms, m.p. 102.5°-104° C.

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.
