Participants

Reaction Steps

A mixture of the product from Example 441, 2-(2-hydroxy-2-phenylethyl)-4-(4-fluorophenyl)-5-[4-(methylsulfonyl)phenyl]-3(2H)-pyridazinone (210 mg, 0.45 mmol), iodomethane (56 μL, 0.90 mmol), and an 80% oil dispersion of sodium hydride (18 mg, 0.59 mmol) in anhydrous DMF (16 mL) was stirred at room temperature for 18 hours. The reaction mixture was partitioned between ethyl acetate and 2 N aqueous hydrochloric acid. The organic layer was washed with brine, dried over MgSO4, and filtered. The filtrate was concentrated in vacuo to provide a yellow oil which was purified by column chromatography (silica gel, 70:30 hexanes/ethyl acetate). Fractions containing product were combined and concentrated in vacuo, and the residue was triturated with hexanes to provide the title compound (yield: 75 mg, 34.7%). mp 135-137° C. 1H NMR (300 MHz, CDCl3) δ 3.07 (s, 3H), 3.26 (s, 3H), 4.33-4.52 (m, 2H), 4.91 (dd, J=9 Hz, 3 Hz, 1H), 6.99 (t, J=9 Hz, 2H), 7.20 (dd, J=9 Hz, 3 Hz, 2H), 7.31-7.50 (m, 7H), 7.87 (s, 1H), 7.89 (d, J=9 Hz, 2H). MS (DCI/NH3) m/z 479 (M+H)+. Anal. calc. for C26H23FN2O4S: C, 65.25; H, 4.84; N, 5.85. Found: C, 64.98; H, 4.83; N, 5.81.
