Reaction Conditions

Reaction Steps

To a round bottom flask equipped with a stir bar, condenser, and a nitrogen inlet 2-cyano-2-(2-nitro-5-phenoxy-benzyl)-hex-5-enoic acid (4.0 g, 10.92 mmol) was added and dissolved in dimethylacetamide (10 mL). The solution was heated to 150° C. for 3 hours. The reaction mixture was allowed to room temperature, then the solvent was removed under reduced pressure. The resulting crude product was dissolved in ethyl acetate and washed 3 times with 1N HCl followed by one wash with saturated brine solution. The organic layer was separated and dried with anhydrous sodium sulfate and the solvent was removed to yield crude material. The crude material was subjected to flash chromatography (mobile phase 9:1 heptane:ethyl acetate) to yield a yellow oil.
