Procedure

To a suspension of the alcohol of Step 1 (100 mg, 0.354 mmol) in benzene (5.0 mL) were added an excess of 2-iodopropane (105 mL) and Ag2CO3 (294 mg, 1.06 mmol). After a period of 18 h at 45° C., the reaction mixture was filtered over celite and washed with CH2CL2. After evaporation, the crude compound was purified by flash chromatography (35% to 40% EtOAc) to provide 70 mg of the title compound.
