発明の名称 (英語) 1-NITRO-3,6-SUBSTITUTED CARBAZOLE, METHOD FOR PRODUCING SAME, AND METHOD FOR PRODUCING 1-AMINOCARBAZOLE
発明の概要(英語) A 1-nitrocarbazole in which a nitro group has been substituted only at the 1-position of a carbazole ring cannot be obtained at a high yield since other isomers are mixed therein. 1.18g of 3,6-dichlorocarbazole was dissolved in a mixed solvent of 15ml of 1,4-dioxane and 15ml of acetic acid. While stirring this solution, 0.69g of sodium nitrite was added in small increments. As the sodium nitrite was added, the solution became a pale yellow suspension, the suspension was heated, and thereafter water was added and a resultant solid was filtered and identified. As a result, the residue was the 1-nitro-3,6-dichlorocarbazole of this compound, and the yield was 98%.
