Procedure
A mixture of 27 g (200 mmol) of isobutylbenzene and 24 mL (215 mmol) of ethyl oxalylchloride underwent Friedel-Crafts acylation reaction in an analogous fashion as described for the synthesis of ethyl 4-phenylbenzoylformate to yield 38 g (81% yield) of ethyl 4-isobutylbenzoylformate as a colorless oil.
