Reaction Steps

To the LDA solution at -78° C., was added dropwise a solution of 5 mL (44 mmoles) of ethyl propionate in 20 mL of THF. Stirring was continued at —78° C. for 1 hour, after which a solution of 10 g (40 mmoles) of p-bromo benzylbromide in 25 mL of THF was added dropwise. Stirring was continued at −78° C. for 2 hours. Water was then added dropwise and the reaction was allowed to warm to room temperature.
