実験手順

To a solution of E3174 (234.58 g, 0.54 mol) in DCM (4500 mL) was added triethylamine (85 mL, 0.59 mol) followed by a solution of trityl chloride (159 g, 0.56 mol) in DCM (800 mL) and the reaction mixture was stirred at rt overnight. The reaction mixture was washed with water, dried (MgSO4), filtered, and concentrated in vacuo. Chromatography over silica eluting with 20-80% acetone/heptane afforded the title compound as an orange solid.
