Procedure

A mixture of EXAMPLE 4C (0.30 g) and (2-(chloromethoxy)ethyl)trimethylsilane (0.094 g) in tetrahydrofuran (4 mL) was treated with triethylamine (0.122 g) at room temperature. The reaction was stirred for 1 hour. The reaction mixture was partitioned between water and ethyl acetate. The aqueous layer was extracted with additional ethyl acetate twice. The combined organic layers were washed with brine, dried over MgSO4, filtered, and concentrated. The residue was purified by flash column chromatography on silica gel eluting with 5% ethyl acetate in hexanes to provide the title compound.
