Versuchsvorschrift

To a solution of 4-{[(4-{[4-chloro-3-(trifluoromethyl)phenyl]oxy}phenyl)methyl]oxy}-2(1H)-pyridinone (80 mg, 0.202 mmol) in N,N-dimethylformamide (1 mL) was added Sodium hydride (80 mg, 2.00 mmol). After stirring at rt for 10 min, bromoethane (100 μL, 1.34 mmol) was added. The reaction mixture was warmed to 80° C. and stirred for 1 h, then cooled to rt, quenched by addition of methanol, concentrated. Purification via Biotage-Qs system afforded the title product (59.5 mg) as a white solid. LC-MS (ESI): m/z 424 [M+H]+; 3.76 min (ret time).
