Glyoxal → HCID 178442959, compound

Participants

Reaction Steps

Approximately 53 grams (0.4 mole) tolyltriazole, 111 grams (0.4 mole) oleyl amine, 100 ml ethanol, and 100 ml toluene were charged to a 1 liter flask equipped with an agitator, Dean-Stark apparatus, and dropping funnel. This mixture was stirred to a homogeneous mixture. Glyoxal (29 grams, 0.2 mole, 40% in water) was added dropwise and then stirred at room temperature for 12 hours. Water was then azeotropically removed by heating to reflux temperatures of approximately 100°-120° C. While maintaining a temperature of less than or equal to 60° C., 56 grams (0.2 mole) oleic acid was added slowly. The reaction mixture was stirred at 60° C. for 1 hour. The orange product (243 grams) was isolated by filtration and removal of solvent under reduced pressure.
