Procedure:
To a solution of ethyl 3-(5-aminopyridin-2-yl)benzoate (7.52 g, 31.06 mmol) in DMF (150 mL) was added N-bromosuccinimide (5.58 g, 31.37 mmol) at 0° C. for 5 min. The reaction mixture was quenched with satd. NaHCO3 solution (150 mL) at 0° C. The mixture was partitioned between ethyl acetate and water. The organic layer was separated and the aqueous layer was extracted with ethyl acetate. The combined organic extracts were washed with brine, dried over MgSO4, filtered and concentrated. The crude product was purified by flash column chromatography using a 85:15 v/v hexane:ethyl acetate as solvent to afford ethyl 3-(5-amino-6-bromopyridin-2-yl)benzoate (8.6 g, 86% yield) as a reddish brown solid.

Procedure:
To 30 ml of ethanol is added 1.79 g of N-acetylcysteamine and with ice-cooling and stirring, 720 mg of sodium hydride (oily, 60 wt.%) is added. Then, 1.54 g of 6-chloroimidazo[1,2-b]pyridazine is further added and the mixture is stirred at 50° C. for 4 hours. The solvent is distilled off under reduced pressure and the residue is diluted with a saturated aqueous solution of sodium hydrogen carbonate and extracted with chloroform. The extract is dried over magnesium sulfate and the solvent is distilled off under reduced pressure. The residue is subjected to silica gel (50 g) column chromatography and after the column is washed with ethyl acetate, elution is carried out with acetone. The eluate is concentrated under reduced pressure to give 1.83 g of 6-(2-acetylaminoethylthio)imidazo[1,2-b]pyridazine as colorless powders.

Procedure:
Into the reactor previously described are charged 49.7 grams (0.315 moles) of p-nitrochlorobenzene together with 98.7 grams of a 66.4% solution of formanilide recovered from a previous run (0.54 molecular proportions). The solution also contained 0.07 moles of p-nitrochlorobenzene, bringing the total to 0.385 mole. About 50 milliliters of xylene are added, and the mixture heated to refluxing temperature which is about 195°-198° C. To the hot mixture is added at the rate of about 0.4 ml. per minute 82.5 grams (0.55 mole) of cesium hydroxide as a 50% solution in water (165 grams) during which addition the water is continuously removed. The heating is continued for a total time of about five hours, then 250 ml. of xylene is added and the xylene solution washed twice with 200 ml. portions of 90° C. water. The xylene solution is cooled to 5° C., filtered and the cake washed with 60 ml. of 5° C. xylene. There is obtained 40.7 grams of 4-nitrodiphenylamine. The total yield determined as described in Example 1 is 72%. The conversion of p-nitrodiphenylamine is 99.1%.
