반응 단계
A mixture of 4-oxo-4,5,6,7-tetrahydro-1H-indole-3-carboxylic acid (179 mg, 1 mmol), aniline (0.46 mL, 5 mmol), and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (959 mg, 5 mmol) in 50% aqueous dioxane (10 mL) was allowed to stir at ambient temperature for 17.5 hours, then concentrated in vacuo. The residue was cooled in an ice water bath, aqueous 3.6 N hydrochloric acid was added, and the precipitate collected, rinsed with aqueous 3.6 N hydrochloric acid then water and dried. Recrystallization from ethyl alcohol afforded N-phenyl-4-oxo-4,5,6,7-tetrahydro-1H-indole-3-carboxamide (Compound 35)(164 mg). mp 225-226° C.
