Hydrochloric Acid → HCID 85608038, compound

Participants

Reaction Steps

A mixture of 4,5,8,9-tetrahydropyrrolo[3,2,1-jk]carbazol-10(7H)-one (364 mg) and hydroxylamine hydrochloride (479 mg) in pyridine (50 ml) was heated to 50° for 60 h, and was then poured into 2N hydrochloric acid (100 ml). The resultant precipitate was filtered off, washed with water (50 ml), and dried in vacuo at 50° for 6 h to give the title compound (140 mg). Filtration of the precipitate that formed subsequently in the filtrate gave a further crop of the title compound (104 mg), m.p. 271°-272°.
