反応手順

To a vial were added successively KOtBu (15.0 mg, 0.13 mmol), [4′-(trifluoromethyl)biphenyl-4-yl]methanol (US Patent 2004209936) (36.0 mg, 0.14 mmol) and DMF (0.3 mL). After 5 min, the title compound from Example 237 Step A (20.0 mg, 0.05 mmol) was added. After 30 min, the reaction mixture was treated with NaOH (0.1 mL, 3 N aqueous, 0.3 mmol), MeOH (0.1 mL) and 1,4-dioxane (0.1 mL) at 50° C. for 20 min. Reverse phase HPLC using a YMC C-18 column (65 to 100% acetonitrile in water, each with 0.1% v/v TFA) gave the title compound: LCMS m/z 584.9 [M+H]+; 1H NMR (400 MHz, CDCl3) δ 8.44 (dd, J=7.6, 1.9 Hz, 1H), 8.31 (d, J=7.8 Hz, 1H), 8.27 (dd, J=4.9, 2.0 Hz, 1H), 8.20 (s, 1H), 7.94 (t, J=7.9 Hz, 1H), 7.69 (s, 4H), 7.62-7.53 (m, 5H), 7.10 (dd, J=7.5, 4.9 Hz, 1H), 5.63 (s, 2H).
