Procedure
In another embodiment, the invention provides a process for preparing N-(4-{4-amino-7-[1-(2-hydroxyethyl)-1H-pyrazol-4-yl]thieno[3,2-c]pyridin-3-yl}phenyl)-N′-(3-fluorophenyl)urea dihydrogen citrate in a solid crystalline form, wherein the crystalline form is Form I. The process comprises a) providing a mixture comprising (i) N-(4-{4-amino-7-[1-(2-hydroxyethyl)-1H-pyrazol-4-yl]thieno[3,2-c]pyridin-3-yl}phenyl)-N′-(3-fluorophenyl)urea, water, acetone, and citric acid; b) causing N-(4-{4-amino-7-[1-(2-hydroxyethyl)-1H-pyrazol-4-yl]thieno[3,2-c]pyridin-3-yl}phenyl)-N′-(3-fluorophenyl)urea dihydrogen citrate crystalline Form I to exist in the mixture. The process can further comprise isolating N-(4-{4-amino-7-[1-(2-hydroxyethyl)-1H-pyrazol-4-yl]thieno[3,2-c]pyridin-3-yl}phenyl)-N′-(3-fluorophenyl)urea dihydrogen citrate in a solid crystalline form, wherein the crystalline form is Form I.
