---|---|---|
31.5% | With sodium hydroxide; In toluene; for 7h;Inert atmosphere; Reflux; | The above-mentioned 2-(4-nitrophenyl) pyridine 4-Bromo-1,2-diaminonaphthalene 4.0 g Caustic soda 1.4 g 50 ml of toluene The reaction vessel was purged with nitrogen and heated to reflux with stirring for 7 hours.100 ml of toluene was added to extract, and the mixture was concentrated under reduced pressure. The residue was purified by column chromatography to obtain 4-bromo-2- {4- (pyridine-2-yl) phenylazo} naphthyl-1-amine (first intermediate halide) was obtained in a yield of 32.9% |
