Participants

Reaction Conditions

Reaction Steps

A mixture of ethyl 2-bromoacetate (0.334 mL 3.01 mmol), 1,2-dibromoethane (0.02 mL, 0.23 mmol), Zn powder (0.227 g, 3.47 mmol) and THF (2.5 mL) was heated to 65° C. for 2 min before cooling to rt. Chlorotrimethylsilane (0.015 mL, 0.116 mmol) was added and the reaction was stirred for 5 min at which point the product of Example 1 (1 g, 2.315 mmol) in THF 10 mL was added. The reaction was heated to 70° C. After 1 h the reaction was cooled to rt. The reaction was diluted with EtOAc and washed with 2 M aq HCl and brine. The concentrated residue was purified by flash chromatography on silica gel gradient eluted with 0-10% EtOAc in CH2Cl2 affording the product (LC-2) HPLC/MS: 520.2 (M+1), 522.2 (M+3); Rt=3.97 min.
