Participants

Reaction Steps

In a round bottom flask fitted with a reflux condenser is placed 4 g of p-dimethylaminobenzoic acid and 8 ml of oxalylchloride. The evolution of gas starts immediately and the spontaneous reaction is run at room temperature for 15 minutes. 8 ml of toluene is added and and the mixture is heated to gentle reflux for one hour. The reaction mixture is then distilled to dryness under reduced pressure to produce a blue-green solid which is washed with ether and dried on a watch glass.
