Embodiment 1
[0047] Cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide fumarate
[0048] Compound cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide 4.1 grams (0.01mol) and fumaric acid 1.17 grams (0.01 mol) was dissolved in 100 ml of boiling ethanol. The hot solution was filtered through diatomaceous earth, then slowly cooled under gentle stirring, and stood for several hours at a temperature of 0-5°C to precipitate cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-benzene Cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidine-4- Amino]phenyl}-amide fumarate crystals were washed with ethanol and dried under vacuum at 50°C to obtain 5.25 g of product.
Embodiment 2
[0050] Cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide fumarate
[0051] Compound cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide fumarate 4.1 grams and fumaric acid 1.17 grams in reflux Stir in 100 ml of 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, cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide rich Mamate salt crystals, cyclopropanecarboxylic acid {3-[6-(3-trifluoromethyl-phenylamino)-pyrimidin-4-ylamino]phenyl}-amide fumarate crystals were filtered off and washed with ethanol and dried under vacuum at 50°C to yield 5.2 g of product.
