Reaction Conditions

Reaction Steps

Sodium borohydride (38 mg, 0.1 mmol) was added to a solution of the product from Example 1F (25 mg, 0.05 mmol) in tetrahydrofuran (3 mL) and ethanol (3 mL) maintained at 0° C. The reaction was allowed to warm to room temperature over 30 min and then stirred at room temperature for 1 hour. After this time the reaction was quenched by addition of water (5 mL) and extracted with ethyl acetate. The organic extracts were combined and washed with water, brine, dried (MgSO4), filtered and concentrated to a brown oil which was purified via flash column (eluting with 15% ethyl acetate in hexanes) to provide the title compound. 1H NMR (500 MHz, DMSO-d6) δ ppm 1.12 (m, 2H), 1.19 (t, J=7.32 Hz, 3H), 1.42-1.99 (m, 22H), 2.22 (d, J=6.71 Hz, 2H), 2.47 (m, 1H), 3.89 (dd, J1=10.38 Hz, J2=7.94 Hz, 1H), 4.02 (m, 1H), 4.06 (q, J=7.32 Hz, 2H), 4.24 (dd, J1=10.37 Hz, J2=2.74 Hz, 1H), 4.71 (s, 1H), 6.07 (s, 1H), 7.28 (d, J=8.24 Hz, 2H), 7.59 (d, J=8.24 Hz, 2H), 12.21 (br s, 1H); MS (ESI) m/z 507.4 [M+H]+.
