Procedure
A mixture of 3.24 g. of sodium methylate, 8.75 g. of β-anilino-propionitrile and 14.9 g. of 4'-[1-hydroxy-2-(methylsulfonyl)-ethyl]-2',6'-dimethoxy-N-methylacetanilide in 60 ml. of absolute dimethylsulfoxide was stirred at 50° C. for 4 hours with the exclusion of moisture. The solution was poured into 600 ml. of water. The resulting emulsion was extracted with two 400 ml. portions of ethyl acetate. Thereafter, the ethyl acetate extracts were washed with two 150 ml. portions of water, combined, dried over magnesium sulfate and evaporated under vacuum. Recrystallization of the residue from ethyl acetate gave 4'-(3-anilino-2-cyano-allyl)-2',6'-dimethoxy-N-methyl-acetanilide having a melting point of 202°-204° C.
