実験手順

2-(4-bromo-2-fluorobenzyl)-6-phenyl-1,2-thiazinane 1,1-dioxide (100 mg, 0.25 mmol), 1-methylsulfonylpiperidin-4-ol (67.2 mg, 0.38 mmol), copper(I) iodide (9.5 mg, 0.05 mmol), 3,4,7,8-tetramethyl-1,10-phenanthroline (24 mg, 0.1 mmol) and cesium carbonate (123 mg, 0.38 mmol) were weighed out in a vial and the vial was purged with nitrogen. p-Xylene (1 mL) was then added and the reaction was stirred at 135° C. for 16 hours. The reaction was then filtered through diatomaceous earth, concentrated and purified by reverse-phase HPLC to give 2-(2-fluoro-4-((1-(methylsulfonyl)piperidin-4-yl)oxy)benzyl)-6-phenyl-1,2-thiazinane 1,1-dioxide (50.1 mg, 40% yield).
