Procedure

A suspension of [4-amino-2-[1-(3-chloro-propane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanone (32 mg, 0.066 mmol, Example 272), potassium iodide (50 mg, 0.3 mmol), N-methylpiperazine (500 mg, 5.0 mmol, Aldrich) in dioxane (15 mL) was heated at reflux under nitrogen for 16 hours. The reaction was diluted with methylene chloride (40 mL) and washed (2×) with water. The organic layer was separated and dried (Na2SO4). The residue was purified by silica gel chromatography (methanol/methylene chloride) and triturated from ethyl ether and filtered to give (4-amino-2-[1-[3-(4-methyl-piperazin-1-yl)-propane-1-sulfonyl]-piperidin-4-ylamino]-pyrimidin-5-yl)-(5-fluoro-2-methoxy-phenyl)-methanone as a white solid (12 mg, 33% yield). HRMS, observed: 550.2612; Calcd for (M+H)+: 550.2607
