실험 절차

A solution of 2,4-pentanedione (51.5 mL), aniline (45.6 mL) and a catalytic amount of para-toluenesulfonic acid monohydrate (0.95 g) in toluene (500 ml) was refluxed for 3.5 h in a round bottom flask equipped with a Dean-Stark apparatus and condenser. The solution was concentrated to dryness to give the desired compound as an orange oil (89.3 g).
