Vol. 68 mixed melting point with fluorenone-hydrazone prepared by the interaction of fluorenone and hydrazine was unchanged; hydrochloride, deep yellow crystals melting at 268= (dec.).Reaction of 9-Chlorofluorene with Piperidine.-Colorless needles were deposited from a solution of 0.5 g. of 9chlorofluorene in 5 cc. of piperidine kept at room temperature for a few hours. The product, 9-(N-piperidino)fluorene, was recrystallized from ethyl alcohol and melted at 99°.
Reduced Mannich Product Derived from V.-The ManFound: C1, 12.0; IT, 14.4. 17.6. Found: C, 45.6; H, 3.81; N, 17.3. nich product was hydrogenated in the usual manner with Summary palladized charcoal catalyst at two atmospheres for two hours using methanol as a solvent. The product after Directions for the synthesis 214-divacuum drying ai: 50 O was a very hygroscopic yellow plastic methyl-8-quinazolyl ketone and 4-hydroxy-8-quinsolid which gave no definite melting point. azoline carboxylic acid from 2-nitroisophthalic The dipicrate of the amino alcohol was prepared from the acid are given. ethereal solutions of both the free base and picric acid, m. p. 92-94'.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
