4-溴-2-甲基萘-1-胺

反应条件: temp:60.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

实验步骤: To a solution of 4-bromo-2-methyl-1-naphthlamine (10 g) in a mixture of concd. hydrochloric acid (14 ml) and water (14 ml) was added dropwise a solution sodium nitrite (2.8 g) in water (7 ml) at -5°-0° C. The diazonium solution was stirred at 0°-5° C an hour. There was added to it an ice-cooled solution of cuprous chloride (4.4 g) in concd. hydrochloric acid (25 ml). The mixture was stirred at 60° C an hour, and the precipitate was extracted with ether and dried. After evaporating the solvent, the residue was distilled to give a colorless oil(5.4 g, 58 %), bp11 127°-132° C. the precipitate was extracted with ether dried After evaporating the solvent the residue was distilled
