Abstract
Monoazaphenanthrene derivatives are prepared by condensing aminomonoazophenanthrenes with o-oxycarboxylic acids of cyclic compounds, or with the corresponding o-acylated carboxylic acid chlorides in the presence of organic diluents and splitting off the acyl radicle. In examples: (1) 9-amino-4-phenanthrene is condensed with 2-oxynaphthalene-3-carboxylic acid in pyridine in presence of phosphorus pentoxide; with 2-acetoxyanthracene-3-carboxylic acid chloride in ether followed by saponification by means of acids or bases; with 3-acetoxydibenzofuran-2-carboxylic acid chloride (prepared by treating the sodium compound of 3-oxydibenzofuran with carbon dioxide, treating the product with acetic anhydride and converting the product to the acid chloride); (2) 10-amino-4-azaphenanthrene is condensed in ether with 2-acetoxynaphthalene-3-carboxylic acid chloride and the acetyl group split off by treating with acids or bases; with 2-acetoxycarbazole-3-carboxylic acid chloride in benzene followed by splitting off of the acetyl group; with 1.3-dimethyl-5-acetoxybenzene-4-carboxylic acid chloride in ether followed by splitting off the acetyl group; with 2-oxycarbazole-3-carboxylic acid in toluene in presence of phosphorus trichloride; with 8-oxyquinoline-7-carboxylic acid (prepared by treating the potassium compound of 8-oxyquinoline with carbon dioxide) in toluene in presence of phosphorus trichloride; (3) 8-amino-4-azaphenanthrene is condensed in pyridine with 2 - acetoxynaphthalene - 3 - carboxylic acid chloride and the acetyl group split off; with acetylsalicylic acid chloride in ether and the acetyl group split off; with 3-oxydibenzofuran-2-carboxylic acid in toluene in presence of phosphorus trichloride; (4) 7-amino-4-azaphenanthrene is condensed in benzene with 2 - acetoxynaphthalene - 3 - carboxylic acid chloride and the acetyl group split off; (5) diamino-1-azaphenanthrene (prepared by nitrating 1-azaphenanthrene and reducing the nitro body) is condensed in pyridine with 2 - acetoxynaphthalene - 3 - carboxylic acid chloride, or with the acid itself in chlorbenzene. The starting materials are prepared according to Specification 451,932 or by nitrating monazaphenanthrenes and reducing.
