Procedure

The product of Step 1 (43 mg) was dissolved in THF (1 ml) and methanol (0.2 ml). Water (0.5 ml) and LiOH (11.95 mg) were added and the reaction was stirred until complete conversion. The reaction was quenched with 1N HCl (0.4 mL) and 5% KHSO4 was added until the pH was 3. The mixture was extracted with ether then ethyl acetate. The combined organics were washed with water (5×) then brine, dried over magnesium sulfate, filtered and concentrated to yield 42 mg of pure product. HRMS (ES+) m/z 848.3522 (M+H)+.
