A study on the synthesis of a benzaldehyde containing an ester function directly from tert-butyl 4-lithiobenzate was described. t-Butyl 4-bromobenzoate reacted with butyllithium at -78°C in THF, followed by immediate addition of DMF to give the desired benzaldehyde in moderate yield. The scope of this reaction was examined.
