실험 절차

A mixture of 5-aminolevulinic acid hydrochloride (1.68 g, 10 mmol), 1,3-cyclohexanedione (1.12 g, 10 mmol) and sodium acetate (1.64 g, 20 mmol) in water (10 mL) was stirred at 110° C. for 4 hr and then cooled. The precipitate which formed was collected by vacuum filtration, washed with 30% of ethanol in water and dried under vacuum to give 1.7 g (82%) of 3-(4-oxo-4,5,6,7-tetrahydro-1H-indol-3-yl)-propionic acid.
