Reaction Steps

116 mg of periodate of sodium in 0.5 cm3 of water are added to a mixture of 200 mg of 1-(6-{[6-(4-fluorophenyl)[1,2,4]triazolo[4,3-b]pyridazin-3-yl]sulphanyl}-1,3-benzothiazol-2-yl)-3-[2-(morpholin-4-yl)ethyl]urea in 5 cm3 of acetic acid at 20° C. After an overnight period, the precipitate is filtered off. The white powder obtained is a mixture containing oxidized product and starting product. This mixture is taken up in 10 cm3 of acetic acid with 155 mg of sodium periodate dissolved in 1 cm3 of water. The mixture is left to stir overnight at 20° C. The precipitate is then filtered off and then washed successively with diisopropyl ether and with diethyl ether. 155 mg of white powder of 1-(6-{[6-(4-fluorophenyl)[1,2,4]triazolo[4,3-b]pyridazin-3-yl]sulphanyl}-1,3-benzothiazol-2-yl)-3-[2-(4-oxidomorpholin-4-yl)ethyl]urea are obtained, the characteristics of which are as follows:
