2-(2-((1,1-Dimethylethyl)dimethylsilyl)oxy)ethyl)-3-(((1,1-dimethylethyl)dimethyl-silyl)oxymethyl)cyclobutanol (160 mg, 0.43 mmol) from Step B was dissolved in 2 mL of methylene chloride and the resultant solution was cooled to 0° C. Triethylamine (120μL) was added, followed by 36 μL of methanesulfonyl chloride. After stirring the reaction mixture for 30 min at 0° C., it was concentrated in vacuo and the residue was purified on a silica gel column eluted with 10% ethyl acetate in hexane to give 180 mg (89% yield) of the title compound.; MS DCI-NH3M/Z: 447 (M+H)+, 464 (M+NH4)+.
