Reaction Steps

A mixture of 4-tert-butyldiphenylsilyloxy-2,3-dimethoxy-5-methyl-6-(10-trityloxydecyl)phenol (8 g), di-tert-butyl dicarbonate (3 g), triethylamine (1 g) and dichloromethane (20 ml) was stirred at 40° C. for 16 hours. After concentration under reduced pressure, the residue was dissolved in tetrahydrofuran (30 ml). Tetrabutylammonium fluoride trihydrate (2 g) was added, and the mixture was stirred at room temperature for 15 minutes. The solvent was distilled off under reduced pressure, and the residue was subjected to column chromatography on silica gel and eluted with hexane/ethyl acetate (7:3) to obtain the desired compound (10 g).
