Procedure

A solution of 1.51 gram (0.0045 mole) of diethyl N,N'-(5-cyano-m-phenylene)dioxamate in 10 ml. of 5% sodium hydroxide solution is stirred for 25 minutes and filtered. To the filtrate is added dilute hydrochloric acid. The resulting precipitate is removed by filtration; weight 0.86 grams. M.P. 230° C.
