Procedure

N-(4-{4-amino-7-[1-(2-hydroxyethyl)-1H-pyrazol-4-yl]thieno[3,2-c]pyridin-3-yl}phenyl)-N′-(3-fluorophenyl)urea free base solid (102.65 mg) was dissolved in 5 mL of THF/water mixture (80/20 v/v) at 70° C. Citric acid (21.94 mg) was added to the solution followed by the slow addition of heptane (7.5 mL). The appearance of a small amount of precipitant formed in the heptane layer was noted. The precipitant dissolved as it fell into the THF/water layer. The solution was cooled to ambient temperatures. Crystalline solids formed after several days at ambient temperatures. Solid was collected by vacuum filtration.
