실험 절차

To a solution of (R)-3-(4-(2-(4-((S)-3-chloro-2-hydroxypropoxy)phenyl)propan-2-yl)phenoxy)propane-1,2-diol (1000 mg, 2.53 mmol) in acetone (8.0 mL) was added 2,2-dimethoxypropane (630 μL, 5.06 mmol) and catalytic amounts of p-toluenesulfonic acid. After 14 h, the reaction mixture was quenched with an aqueous solution of sodium chloride and stirred for 15 min, and the resulting mixture was extracted twice with ethyl acetate. The organic phases were combined, dried over anhydrous magnesium sulfate and filtered. Solvents were evaporated, and the resulting crude material was purified by silica gel flash chromatography (eluent: 2% methanol in dichloromethane) to provide the title compound.
