Reaction Steps

To a solution of (S)-3,5-dichloro-4-(2-(4-(difluoromethoxy)-3-hydroxyphenyl)-2-(2-(1,3-dioxoisoindolin-2-yl)acetoxy)ethyl)pyridine 1-oxide (155 mg, 0.280 mmol) in DMF (3.8 ml), potassium carbonate (46.5 mg, 0.336 mmol) was added, and the mixture stirred at RT for 30 minutes. Tetrahydrofuran-3-yl 4-methylbenzenesulfonate (224 mg, 0.924 mmol) was added, and the mixture stirred at RT overnight. Water was added, and the aqueous phase extracted with AcOEt (2×). The organic phase was washed with brine, dried and evaporated under reduced pressure. The crude was purified through preparative HPLC (Method 2) to give 17 mg of title compound (yield 10%). 1H NMR (400 MHz, DMSO-d6) δ ppm 8.45 (s, 2H), 7.92 (d, J=4.41 Hz, 4H), 7.18-7.27 (m, 1H), 7.05 (m, 2H), 6.98 (d, J=7.94 Hz, 1H), 6.02 (dd, J=8.38, 4.85 Hz, 1H), 5.12 (m, 1H), 4.30-4.58 (m, 2H), 3.62-4.06 (m, 4H), 3.14-3.43 (m, 2H), 2.20 (ddd, J=13.56, 6.73, 6.62 Hz, 1H), 1.86-2.05 (m, 1H).
