Reaction Steps

The mixture of [4-amino-2-(piperidin-4-ylamino)-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanone (100 mg, 0.290 mmol, Example 59), 1,4-butane sultone (81 uL, 0.870 mmol, Aldrich) and triethylamine (41 uL, 0.290 mmol) in tetrahydrofuran (3 mL) was heated at 150° C. for 1 hour using the Smith Creator microwave synthesizer. Upon cooling to room temperature, the reaction mixture was concentrated. Purification of the crude residue by reverse phase HPLC (C18, eluting with water and acetonitrile) gave [4-amino-2-[1-(4-hydroxy-butane-1-sulfonyl)-piperidin-4-ylamino]-pyrimidin-5-yl]-(5-fluoro-2-methoxy-phenyl)-methanone as white solids (120 mg, 86%). HR-MS (ES, m/z) calculated for C21H29N5O5SF [(M+H)+]482.Example 221, observed 482.1874.
