HCID 86734812HCID 86734812, compound

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-cyanoacrylic acid propargyl ester in 100 ml. of propargyl alcohol and holding the mixture under reflux for 2 hours to obtain 2-benzoxazolinylidene-cyanoacetic acid propargyl ester of melting point 258°-259° C. (decomposition) (from acetone).

Workup

  1. temperatureunder reflux for 2 hours
