Reaction Steps

At −78° C., lithium bis(trimethylsilyl)amide (1.0 M in hexanes) (4 mL, 26 mmol) was added slowly to a solution of methyl 2-(trimethylsilyl)acetate (4 g, 26 mmol) in THF (20 mL). The reaction mixture was maintained at −78° C. for 22 minutes. 1.2 (3.5 g, 15 mmol) in THF (20 mL) was then added slowly to the mixture. The mixture was stirred at −78° C. and allowed to warm to room temperature overnight. The reaction mixture was then poured into water (30 mL) and extracted with EtOAc (300 mL). The organic layers were washed with brine and dried over anhydrous sodium sulfate. After removing solvent by rotary evaporation, the residue was purified by column chromatography (1:4 EtOAc/hexane). The Product 1.3 was obtained in 38% yield as a white solid.
