Reaction Steps
To a solution of 2-ethyl-1-hexanol (65 mg, 0.5 mmol) in THF (15 mL) at room temperature was added NaH (60% oil suspension) (20 mg, 0.5 mmol) and after 10 minutes 2-(4-fluorophenyl)-4-tosyloxy-5-[4-(methylsulfonyl)phenyl]-3(2H)-pyridazinone (193 mg, 0.5 mmol) was added. The resulting mixture was stirred at room temperature for the next 2 hours. The mixture was quenched with 10% citric acid and extracted with ethyl acetate. The extract was washed with water, brine, dried with MgSO4, and purified by chromatography (silica gel, 2:1 hexanes-ethyl acetate) to provide the desired product (yield: 140 mg, 60%). mp 120-122° C. 1H NMR (300 MHz, DMSO-d6) δ 0.75 (m, 6H), 1.1 (m, 6H), 1.20 (quintet, J=7 Hz, 2H), 1.44 (m, 1H), 3.27 (s, 3H), 4.30 (d, J=6 Hz, 2H), 7.37 (t, J=9 Hz, 2H), 7.65 (m, 2H), 7.89 (d, J=9 Hz, 2H), 8.06 (d, J=9 Hz, 2H), 8.18 (s, 1H).
