실험 절차

To the product of EXAMPLE 42 (28 mg) in THF (0.5 mL) at 0° C. was added NaH (5 mg, 60% dispersion in mineral oil). The reaction stirred 10 minutes before acetyl chloride (7 μL) was added. Two hours later an additional 20 μL portion of acetyl chloride was added and again after an additional 90 minutes. After an additional hour of reaction time the reaction was diluted with EtOAc and washed with saturated aqueous NaHCO3 solution and dried (Na2SO4). The concentrated residue was purified by preparative TLC on silica gel eluted with 70% EtOAc in hexane affording the title compound. HPLC/MS: 528.0 (M+1), 530.0 (M+3); Rt=4.27 min.
