实验步骤: The 1-(6-thiocyanato-1,3-benzothiazol-2-yl)-3-[2-(4-methylpiperazin-1-yl)ethyl]urea was prepared according to the method described in Example 9c, but using 982 mg of phenyl(6-thiocyanato-1,3-benzothiazol-2-yl)carbamate and 473 mg of 2-(4-methylpiperazin-1-yl)ethylamine. The residue obtained is chromatographed on a Merck cartridge (25 g of silica 15-40 μm), elution being carried out with a 90/10 mixture of dichloromethane/methanol. 1.13 g of 1-(6-thiocyanato-1,3-benzothiazol-2-yl)-3-[2-(4-methylpiperazin-1-yl)ethyl]urea are thus recovered in the form of a white solid, the characteristics of which are as follows: The residue obtained is chromatographed on a Merck cartridge (25 g of silica 15-40 μm), elution being carried out with a 90/10 mixture of dichloromethane/methanol 1.13 g of 1-(6-thiocyanato-1,3-benzothiazol-2-yl)-3-[2-(4-methylpiperazin-1-yl)ethyl]urea are thus recovered in the form of a white solid

实验步骤: 3 g of ethyl [3,5-bis(2-hydroxyphenyl)-[1,2,4]triazol-1-yl]acetate (Example 2) and 2.5 g of 2-(4-methylpiperazin-1-yl)ethylamine are boiled under reflux for 20 h in 40 ml of ethanol. The mixture is cooled, poured onto water and extracted with ethyl acetate. The combined organic phases are dried over sodium sulfate and concentrated on a rotary evaporator. The residue is chromatographed on silica gel. After concentration and drying, 2-[3,5-bis(2-hydroxy-phenyl)-[1,2,4]triazol-1-yl]-N-[2-(4-methylpiperazin-1-yl)ethyl]acetamide is obtained as a colorless foam.
