Versuchsvorschrift

HClO4 (1.17 mL, 13.6 mmol) is added to a suspension of 48k (3.40 g, 9.06 mmol) in t-butyl acetate (100 mL) and DCM (150 mL). The reaction mixture is stirred at RT overnight then is diluted with EtOAc (150 mL). The solution is washed twice with aqueous 5% NaHCO3 solution, dried (MgSO4), filtered and concentrated under reduced pressure. The residue is purified by flash chromatography (Combi-Flash; EtOAc/hexane) to give t-butylether 481 (2.76 g, 71% yield) as a white solid.
