Reaction Steps
cis-3,3-Dibromo-2-oxobicyclo[4.2.0]octane-1-acetic acid ethyl ester (14.16 g) lithium bromide (4.88 g, 56.21 mmol), and lithium carbonate (2.98 g, 14.4 mmol) were dissolved in 47.3 mL of DMF under nitrogen and heated to 100° C. for 5 minutes. The reaction mixture was then poured into 500 mL of water and extracted with 4×100 mL of toluene. The organic phase washed with 4×100 mL of water, dried over MgSO4, and concentrated in vacuo affording 8.86 g (80%) of product.
