Participants

Reaction Steps

With cooling with ice, potassium hexamethyldisilazide (0.5 M toluene solution, 89 mL) was dropwise added to a stirring THF (100 mL) solution of the compound (10.0 g, 37.0 mmol) synthesized in the above (1) and t-butyldimethylchlorosilane (6.13 g, 40.7 mmol), and then the reaction solution was stirred at room temperature for 12 hours. The reaction solution was poured into water, extracted with ethyl acetate, the organic layer was washed with saturated saline, and dried with magnesium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel flash column chromatography (hexane) to obtain the entitled compound (13.5 g, 95%) as a white solid.
