Reaktionsschritte
The compound obtained in (2) (24.4 g) was dissolved in THF (200 mL), tetrabutylammonium fluoride (hereinafter sometimes referred to as TBAF) (a 1.0 M THF solution, 62.7 mL) was added under stirring, and stirring was continued for 1 hour. The reaction solution was concentrated under reduced pressure, and the resulting residue was purified by flash chromatography (ethyl acetate/hexane=25%→100%) using an amino column (trade name: Hi-Flash Column 5L Amino, manufactured by Yamazen Corporation) to give the title compound (14.1 g).
