Reaction Steps

A suspension of acetic acid 3-[4-[4-amino-5-(5-fluoro-2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-sulfonyl]-propyl ester (25 mg, 0.049 mmol, Example 274) in a solution of potassium hydroxide (50 mg, 0.9 mmol), water (1 mL) and ethanol (6 mL) was stirred at 25° C. for 1 hour. The solution was cooled, acidified with acetic acid and reduced in volume to 2 mL. This was diluted with water and the product extracted into methylene chloride. After washing with water, the organic layer was separated and dried (Na2SO4). The residue was purified by silica gel chromatography (ethyl acetate) and crystallized from methylene chloride/hexane to give [4-amino-2-[1-(3-hydroxy-propane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanoneas a white solid (12 mg, 50% yield). HRMS, observed: 468.1716; Calcd for (M+H)+: 468.1712
