Reaction Steps

To a solution of 5-t-butyldiphenylsilyloxy-1-[2-(N,N-diphenylcarbamoyloxy)ethyl]-2-oxo-1,2,3,4-tetrahydronaphthalene (0.9 g) in THF (tetrahydrofuran) (20 ml) was added methylmagnesium bromide (2.0 ml, 1M solution in THF) at 0° C. under N2. After being stirred for 1 hour at the room temperature, the solution was poured into a mixture of ethyl acetate and water. The organic layer was washed with 1N--HCl solution, sat. NaHCO3, and brine, dried over MgSO4, and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 5-t-butyl-diphenylsilyloxy-1-[2-(N,N-diphenylcarbamoyloxy)ethyl]-2-hydroxy-2-methyl-1,2,3,4-tetrahydronaphthalene (0.6 g).
