[4-Amino-2-[1-(3-chloro-propane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(2,3-difluoro-6-methoxy-phenyl)-methanone (Example 226) was reacted with sodium acetate in an analogous manner as described in Example 227 to give acetic acid 3-[4-[4-amino-5-(2,3-difluoro-6-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-sulfonyl]-propyl ester. The crude acetic acid 3-[4-[4-amino-5-(2,3-difluoro-6-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-sulfonyl]-propyl ester was hydrolyzed with 5% potassium hydroxide to give [4-amino-2-[1-(3-hydroxy-propane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(2,3-difluoro-6-methoxy-phenyl)-methanone. HR-MS (ES, m/z) calculated for C20H26N5O5SF2 [(M+H)+] 486.1617, observed 486.1623.
