To it was dropwise added N,N-diisopropylethylamine (0.07 mL, 0.38 mmol). The reaction mixture was allowed to stir at 0° C. for 5 min, and then partitioned between EtOAc and 5% LiCl aqueous solution. The organic layer was separated, washed with NaHCO3 (saturated aqueous) and brine. After dried over MgSO4, it was filtered and concentrated. The residue was purified by silica gel chromatography eluting with EtOAc/hexanes to afford the title product. MS (m/z): 644.33[M+H]+.
