Reaction Steps

A mixture of 4-{4-[8-(3-methanesulfonyl-propoxy)-imidazo[1,2-a]pyridine-3-yl]-pyrimidin-2-ylamino}-cyclohexanecarboxylic acid ethyl ester (0.1 g) and LiOH—H2O (42 mg) in THF (20 mL), EtOH (5 mL) and water (5 mL) was stirred at RT overnight. The reaction mixture was then concentrated, diluted with water, neutralized with HCl (1 N), and the resulting solid filtered and dried at 50° C. under vacuum overnight to provide 4-{4-[8-(3-methanesulfonyl-propoxy)-imidazo[1,2-a]pyridine-3-yl]-pyrimidin-2-ylamino}-cyclohexanecarboxylic acid (90 mg), which was used without further purification.
