Participants

Reaction Steps

A suspension of [4-amino-2-[1-(3-chloro-propane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanone (80 mg, 0.16 mmol, Example 273), potassium iodide (100 mg, 0.61 mmol), and potassium acetate (120 mg, 1.22 mmol) in dimethylformamide (6 mL) was heated at 65–85° C. under nitrogen for 14 hours. The resulting solution was diluted with 50 mL of cold water plus 20 mL of saturated aqueous sodium chloride. Solids were filtered, collected and dissolved in methylene chloride. After washing with water, the organic layer was separated and dried (Na2SO4). The residue was purified by silica gel chromatography (ethyl acetate/hexane) and crystallized from methylene chloride/ethyl ether to give acetic acid 3-[4-[4-amino-5-(5-fluoro-2-methoxy-benzoyl)-pyrimidin-2-ylamino]-piperidine-1-sulfonyl]-propyl ester as a white solid (42 mg, 51% yield). HRMS, observed: 510.1822; Calcd for (M+H)+: 510.1817
