Procedure

The procedure described in Example 1 is repeated using, instead of 3,3-bis(methylthio)-2-cyanoacrylonitrile, an equivalent amount of 3,3-bis(methylthio)-2-cyanoacrylamide and holding the mixture under reflux for 12 hours to obtain 2-benzoxazolinylidene-cyanoacetic acid amide of melting point 220°-222° C. (dec.) (from methanol).
