참여 물질

반응 단계

The reaction scheme (CCLXIX) illustrates a synthetic process rthat included dropwise adding of 6.4 g bromine (40 mmol) to a solution of 4-nitrobenzene-1,3-diamine (5.56 g, 36.3 mmol), in 50 mL 1,4-dioxane, followed by stirring the solution was room temperature for 16 h. The yellow precipitate was isolated by filtration, washed with 1,4-dioxane (30 mL) and dried in vacuo to give 4-bromo-6-nitro-benzene-1,3-diamine dihydrobromide salt designated on the reaction scheme (CCLXIX) as compound 13 (8 g, 95%).
