Reaction Steps

To a solution of Example 72A (50 mg, 0.108 mmol) in DMF (1 mL) was added NaH (7.7 mg, 0.32 mmol) and the mixture was stirred at room temperature for 30 minutes. Then (bromomethyl)cyclopropane (43.6 mg, 0.323 mmol) was added and the mixture was stirred at 50° C. for 18 hours. Water (10 mL) was added and the mixture extracted with ethyl acetate (3×15 mL). The combined organics were washed with brine, dried (MgSO4), filtered, and concentrated. The residue was purified by HPLC (C18, CH3CN/water (0.1% NH4HCO3), 40-60%) to provide the title compound (5 mg, 8.96% yield). 1H NMR (400 MHz, CD3OD) δ 7.46 (s, 1H), 7.28 (dd, J=6.9, 2.6 Hz, 2H), 6.92 (dd, J=12.2, 8.4 Hz, 2H), 6.80 (d, J=9.6 Hz, 2H), 5.81 (s, 1H), 3.87 (q, J=7.0 Hz, 2H), 3.43 (d, J=7.1 Hz, 2H), 3.38 (s, 3H), 3.00 (q, J=7.4 Hz, 2H), 1.22 (t, J=7.4 Hz, 3H), 1.14 (t, J=7.0 Hz, 3H), 0.81 (d, J=7.8 Hz, 1H), 0.33 (dd, J=8.0, 1.2 Hz, 2H), 0.01 (d, J=5.9 Hz, 2H). MS (ESI+) m/z 519.2 (M+H)+.
