Purpose: 1 intermediates in organic synthesis. Two pharmaceutical intermediates, also can be in EPA8081A method analysis of organochlorine pesticides in water and soil to internal standard.
Production methods: the adjacent nitroaniline by the following steps. Neighbouring nitroaniline and a mixture of sulfuric acid cooling to 0 to 5 ℃, slowly add sodium nitrite solution under stirring, potassium iodide to the reaction of starch test paper turned blue. Will the diazonium salt solution under stirring slowly add 40 ℃ of cuprous bromide solution. After cooling, were extracted with ether extract with alkali, hydrochloric acid solution and water washing, a quick product after recovery of ethyl ether. The yield of about 70%.
