実験手順
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-cyanoacrylic acid morpholide and holding the mixture under reflux for 24 hours to obtain 2-benzoxazolinylidene-cyanoacetic acid morpholide of melting point 217°-219° C. (from ethanol).
