Reaction Steps

To a stirred solution of N-(4-(5,5-dimethyl-4-oxo-3-(4-(quinolin-2-ylmethoxy)phenyl)-4,5-dihydrofuran-2-yl)phenyl)-N-(methylsulfonyl)methane sulfonamide (40 mg, 0.06 mmol) in THF: H2O (6 mL) was added 2N NaOH (1.0 mL) at 0° C. under N2 atmosphere. The reaction mixture was stirred at 0° C. for 10 min. Upon complete consumption of the starting material (by TLC), the reaction mixture was diluted with water and extracted with EtOAc (2×15 mL). The combined organic layers were washed with water (2×5 mL), brine and dried over anhydrous Na2SO4. After filtration and evaporation, the crude material was purified by silica gel column chromatography to afford N-(4-(5,5-dimethyl-4-oxo-3-(4-(quinolin-2-ylmethoxy)phenyl)-4,5-dihydrofuran-2-yl) phenyl)methane sulfonamide (20 mg, 26%), as a pale yellow solid. 1H NMR (500 MHz, CDCl3): δ 8.45 (d, J=8.5 Hz, 1H), 8.12 (t, J=7.9 Hz, 1H), 7.78 (t, J=8.4 Hz, 1H), 7.70 (d, J=8.2 Hz, 1H), 7.64 (t, J=8.2 Hz, 1H), 7.44 (d, J=8.5 Hz, 2H), 7.18 (d, J=7.5 Hz, 2H), 7.10 (d, J=7.5 Hz, 2H), 6.98 (d, J=8.2 Hz, 2H), 5.42 (s, 2H), 2.85 (s, 3H), 1.44 (s, 6H). MS: [M+Na]: m/z=537.3, [M+H]: m/z=515.2 HPLC: 95.7% (RT-2.37 min),
