Reaction Steps
To an ice-cold solution of 11.4 grams (0.1 mole) of 1,2-diaminocyclohexane and 5 ml of water was added dropwise 8.3 grams of 40% aqueous glyoxal (2.9 grams, 0.05 mole). Within 5-10 minutes a precipitate formed, which was allowed to stand at room temperature for one hour, then heated at 65°-70° C. for 1.5 hours. The solid was recrystallized from acetonitrile to give 1.05 grams of tan crystals, m.p. 148°-155° C.
