Embodiment 1

[0049] 3-(4-Acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinoline fumarate

[0050] Compound 3-(4-acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinoline 47.3 grams (0.1mol) and fumaric acid 11.7 ( 0.1mol) gram dissolved in 1000ml of boiling ethanol. The hot solution was filtered through diatomaceous earth, then slowly cooled under gentle stirring, and stood at a temperature of 0-5°C for several hours to precipitate 3-(4-acetylazin-1-yl)-5-(3 -Nitrobenzylamino)-7-trifluoromethyl-quinoline fumarate crystals, 3-(4-acetylpiperazin-1-yl)-5-(3-nitrobenzylamino )-7-trifluoromethyl-quinoline fumarate crystals, washed with ethanol and dried under vacuum at 50°C, yielding 57.9 g of product.

Embodiment 2

[0052] 3-(4-Acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinoline fumarate

[0053] Compound 3-(4-acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinoline fumarate 47.8 grams and fumaric acid 11.7 grams Stir in 1000 ml of refluxing ethanol until all solids are dissolved. Add activated carbon, filter the hot solution through diatomaceous earth, and cool down to room temperature while stirring. Standing for several hours in a temperature environment of 0-5°C, 3-(4-acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinolin phenoline fumarate crystals, 3-(4-acetylpiperazin-1-yl)-5-(3-nitrobenzylamino)-7-trifluoromethyl-quinoline fumarate crystals were filtered off , washed with ethanol and dried under vacuum at 50°C to yield 57.2 g of product.
