Reaction Steps

To 1-tert-butyl 7-ethyl 2-acetyl-2-(3-cyanobenzoyl)-heptanedioate (4.2 g) was added trifluoroacetic acid (20 mL) in an ice-water bath. After 30 minutes, the bath was removed and the reaction mixture was stirred at ambient temperature. After 1 hour, the mixture was concentrated. The residue was dissolved in toluene and was evaporated in vacuo to give ethyl 6-(3-cyanobenzoyl)-7-oxooctanoate (3.20 g, 100.4%) as colorless oil.
