Embodiment 1

[0047] Apoprofen fumarate

[0048] Dissolve 3.61 g (0.01 mol) of the compound apoprofen and 1.17 g (0.01 mol) of fumaric acid in 100 ml of boiling ethanol. The hot solution is filtered through diatomaceous earth, then slowly cooled under gentle stirring, and left to stand for several hours at a temperature of 0-5°C to precipitate apoprofen fumarate crystals, and apoprofen fumarate is filtered out Salt crystals were washed with ethanol and dried under vacuum at 50°C to obtain 4.76 g of product.

Embodiment 2

[0050] Apoprofen fumarate

[0051] Stir 3.61 g of the compound apoprofen fumarate and 1.17 g of fumaric acid in 100 ml of refluxing ethanol until all the solids are dissolved. Add activated carbon, filter the hot solution through diatomaceous earth, and cool down to room temperature while stirring. After standing for several hours in a temperature environment of 0-5°C, the crystals of apoantifen fumarate are precipitated, and the crystals of apoantifen fumarate are filtered out, washed with ethanol and dried under vacuum at 50°C to obtain 4.74 g of product.
