The reaction was carried out for 00 hours. To this, 50117 ethyl acetate and 40% water were added and mixed well. After standing still, the bead layer was collected, topped with an organic solvent, and the obtained solid was dissolved in a mixed solvent of chloroform and methanol at a ratio of 8:2. A silica gel column was applied to obtain a fraction corresponding to n-decyl-β-D-galactoside. This was applied to a rotary evaporator to remove the solvent, and the resulting solid was trimethylsilylated and subjected to gas chromatography and GC-MAS to n-decyl-β-
Production of D-galactoside was confirmed. The product obtained was 0.1 g, with a molar yield of 5.6%.
