Procedure

A mixture of m-phenylenediamine (10.8 grams) 0.10 ml.) and diethyl oxalate (50 ml.) is refluxed for 2.5 hours. The cooled reaction mixture is diluted with ether (200 ml.) and the crude product collected (19.2 grams, M.P. 150° C.). Two recrystallizations from methanol give off white crystals (6.65 grams, 155°-160° ).
